Best Senior Pranks- Highschool Pranks

Senior Pranks

Senior pranks tend to be an unofficial tradition at most high schools, similar to the unofficial senior skip day. It is crucial to find the perfect prank; one must realized the fine line between mischievous and vandalism or criminal.

No senior prank should cause harm to a living creature and all of the students should be willing to pay for any accidental damages that may result from the prank.

Off the top of my head I can think of a few funny senior pranks:

  • Bubble bath in the school fountain.
  • Let mice run through the halls (but this may fall under that no harm to a living creature rule depending on how the prank's carried out)
  • Let thousands of crickets loose in the halls (crickets are actually rather cheap in bulk)
  • Tuna in the ventilation ducts (best if done before a long break- winter or spring)
  • Fill a tree in the front of the school with bras of jock straps
School desks were placed outside to fill up the courtyard area.

Best Senior Pranks

Some of the better senior pranks take work, time, and energy. But, if you want to be noticed and remembered as a school legacy, these will definitely be the ones you will want to consider.


Taking something large a part and reassemble it in an impossible location. Usually, cars on roofs are a popular choice. But, remember the larger the object and the smaller the location, the better the prank.


Rewire or reprogram things to behave erratically or unexpectedly. Usually one would consider changing morning announcements, bell schedules, and video broadcasts. But, again, no prank should result in the harm of the school's technology equipment.


Subtle pranks pulled off during the graduation ceremony. These pranks should not disrupt or demean the ceremony, as it may result in the holding of your diploma (yes even after technically graduating, the officials can hold back your diploma). You may consider handing small items, such as pennies with the year, jelly beans, or other small trinkets to the principal or other official as each graduate goes to shake their hand.


Fill a space with an unusual or unexpected object. These pranks can be quite humorous. You may consider placing a ton of "For Sale" signs on the school's lawn; filling your Principal's office with balloons, popcorn, or styrofoam peanuts; write the graduation year on every car in the parking lot with a mild soap or specialized marker.

Spell out your graduating year with plastic forks.

Pick popular teachers and fill their room, so when they come in the next day, they'll be in for a surprise. Try filling a room with saran wrap.

Capture the rival school's mascot. Dress the rival mascot in your school's colors or altering its appearance n any way to pay homage to your school. If you choose a mascot prank, make sure not to do any real harm to the mascot, as it is still a school's property.


Pay homage to your graduation year. Put salt rock on the grass and write out your graduation year. The salt rock will kill the grass with a day or so, and the year will soon appear.


Have a number of smaller pranks coordinated to wreak havoc on your school in a short period of time. By coordinating many small pranks in one day, you will be noted as a prank mastermind. Plus, it allows for different social groups to each play their own prank on a specified day. Everyone is involved in the fun.


Pranks that involve animals make the festivities all the more interesting. A class animal prank would include a cow, pig, or chicken being let loose through the school. You may consider several animals being released throughout the school, or have school teachers and officials looking for a missing animal. Let 9 baby pigs loose in the school, have each number randomly through 10; one number will be left out but that pig doesn't exist. But, remember if you decide to use animals in your senior prank, make sure that no animal is harmed.

The picture of the chickens in the hallway...I had to look closely because I could have sworn that it was taken at my school! That was my 2010 senior class prank! But the funniest part was seeing the school security officers chasing the chickens around the quads while we sat inside of the classrooms watching though the windows

c/o 2014 on May 12, 2012:

When I was a Freshman, The Seniors(c/o 2011) threw BBQ sauce, ketchup, and eggs everywhere around the school. Now that I am a Sophomore, the Seniors(c/o 2012), they put desks and chairs in the middle of the courtyard. They also threw toilet paper around the school and brung fireworks(the one that pops a lot) to school, and made everyone think they were gun shots. They also put 2012 with some type of liquid in the courtyard, but it won't go away. I was thinking of putting all the golf carts upstairs, have races with them, and leave them up there. The spray paint c/o 2014 in the courtyard(Seniors was an epic fail) then go to the culinary room and cook up all the food...

invisible class on May 02, 2012:

Senior Year is ending and my schools seniors have lost their spirit; so much has happened to my class that its ridiculous. But the effects of this is that most are too scared to pull a senior prank or just don't want to do it. For a moment I would have agreed to not doing a senior prank, but why should I??? This senior year has been horrible i admit, but I feel as if its up to us as seniors to end it off right. We have been talking about how our senior prank was going to be big since freshman year. . . and now that its here, its time to stand up instead of retreating.

It is of vital importance that we seniors prove to our underclassmen that we are the BEST CLASS. When a freshman says your class is lame, something isn’t right. The blatant disrespect for my class has gone on far enough. This is the first year that i haven’t witnessed underclassmen being nervous about the upcoming senior prank week. As I talked to some they mentioned the class of 2012 as being lame, basically saying our existence in the school is unknown. Really?? Really now? Come on? 2012 is THE BEST. In realizing what others younger than us say about our class, it has officially ignited the flame within me, and now I’m burning with the desire to prove them all wrong.

Historical Prank underway

Haha on April 24, 2012:

Every senior go to school early and park your car in multiple parking spots.

Dylan on April 24, 2012:

Marching band wents through the halls one period.

MissPriss;) on April 23, 2012:

my school is locked when school lets out and there are cameras everywhere; inside and out.there has to be SOMETHING we can do and pull off someone help!!

angles on April 17, 2012:

so i was thinking of putting a fish or some kind of rotted cheese (preferably blue) in the AC so that when they open the AC's in the morning the whole corridor would stink

Da hacker called IssI on April 08, 2012:

@Spaceah Hack the computer camera system so it shows different images. Imagine the possibilities.... Got a much-hated teacher? make em vandalize the school on camera!(Note: THey wouldn't actually do this, but cameras never lie, do they =?) This would take a lotta work thou... =/

Spaceah on April 02, 2012:

In my school there are cameras everywhere! So I'm gonna have to create a nifty plan, any ideas? Remember cameras everywhere.

Samantha(: on April 01, 2012:

My boyfriend (at the time) graduated last year (2011) and him and his best friend TP'd the whole first floor of the school; and on the 2nd and 3rd floor opened every locker, and taped all the desks together and put them in the middle of every class room. -I will pull off a better one next year though. :D haha

BITCHFACE2114 on March 14, 2012:

The seniors at my school(class of 2012) taped a bunch of used pads to one of the willow trees in the front of our school and left a sign on it saying pussy willow. the next day they had to take them down but no one wanted to so the burned them on the tree. the tree is ok but the whole outside are of the school smelled like period times 300. it was horrible and still is. its been 2 weeks since they burned them and it stills smells horrible. not as but but still horrible. Im hoping my senior year us seniors(class of 2015) will do something amazing that everyone in america or at least the state or city will hear about. and we will forever be known as senior prank legends!


Wonderloo2012 on March 11, 2012:

My freshman year the seniors spilled hundreds of little call cards with pics of naked women in every hall when the bells rang from our 3rd period it was awesome seeing all the teachers on the ground trying to pick them up! The cards ended up in a bunch of lockers so we would see an occasional card every now and then

Classof2012 on March 09, 2012:

A couple of years ago seniors from our school did the pig thing and one of the pigs died great for a lua not for school.

ArchAngel on March 08, 2012:

Ooooh yah i think im going to the bull thing but in this B--- techers room who hates me

a Very Funny girl on February 26, 2012:

Fill the school toilets with red food dye. fill it so that the dye makes the toilet water look like blood. Then add bits of ketchup to look like blood clumps. I believe this will work especially well in the girls' restrooms. And even better if you go to a private Christian school,(Get it? Like Moses' bloody river. Or maybe that's a bit much?)there were no good suggestions for private schools or boarding schools specifically. Shame really. You can do the most (legal) damage in a boarding school.

xoxo on February 18, 2012:

Last year, the seniors in my school took off all the doors from every classroom and flipped over all the desks. A lot of teachers were really pissed because they couldn't find the doors but they only targeted the asshole teachers so it's all good.

Fisher Thane on January 03, 2012:

At my school the seniors took all the desks and chairs and scattered then randomly around the campus. The whole school missed three blocks getting the chairs and tables back

Cuervo on December 05, 2011:

Back in 1994 when I graduated someone had a junked car spray painted with "1994", "Seniors", the name of my HS etc. placed in the courtyard of the high school I went to.

2013333 on October 02, 2011:

so one year our rival school planted a dogwood tree in the middle of our football field before homecoming.. well dogwood is our state tree so state troopers had to travel 200 miles that day to dig it up beore the game.. this year we are getting them back! so find your state tree b/c in most states its illegal to dig up the state tree with out permission. hahah

alex on September 18, 2011:

All seniors wear roller skates to school. Or The seniors at my school switched for a day with the seniors at the other school in our district. It was hilarious.

2011 on September 03, 2011:

Well, we put instant potatoes on the lawn the night before it rained, dish soap down the halls, put laxatives in the communion, unrolled the toilet paper in the teachers lounge signed it and rolled it back up, put bubble wrap on the floor then packing peanuts and balloons (static attack), sneaky pinned the whole school, replaced all the books in the library with baby books, put baby power in air ducts

chance on August 27, 2011:

i like the idea of doing small pranks throughout of the year. I might do all of them. on of the ideas is to put wet cat food into the heating vents during winter break, and wait til everyone comes back.OMFG!!! this is gonna be awesome. and that thing when they hand out diplomas, give the principal a condom once we go up, and shake his hand. and finally to end the year off, me and my friends leave early, and on the way out, pull the fire alarm. class of 2015 at fhhs, be prepared for one hell of a year.

2-0-1-3 on August 21, 2011:

My school is outdoors and doesn't have any hallways, many of these pranks woudnt here at MP. Any good outdoor prank ideas. and we do have three pools and a big forum.

Reba on August 14, 2011:

This year we are going to drive lawnmowers and atvs to school. We are bringing grills and having a cookout and bringing kiddie pools. Its like one big pool party with a bunch of little pools.

SeNiOr on July 11, 2011:

Our class was thinking instead of one major prank, why not do a ton of little pranks throughout the year. One of them being our school colors are red and white so on the first day of school all the seniors are going to dress up like wheres waldo? and roam the school pretending to look for the waldo. Also we are talking about not driving on the first day so we all take busses and since busses cant refuse a kid, they may have to take many trips and delay the start of school.

walas on June 26, 2011:

i havn't done anything with it yet, but someone should put frozen shaving cream somewhere. not shaving gel, shaving CREAM. coz when shaving cream has been frozen, when it defrosts, it expands 3x it's volume. :)

nanuperez on May 24, 2011:

well i was talking to my dad and he said to get with the principal,city police and a couple tow truck companys and move all of the teachers cars to a parking lot across the street. this years seniors only stacked all the garbage cans in the whole school and put all the benches in front of the exits so every one trips kinda lame but cool

Thompson on May 23, 2011:

We started with wrapping our headmaster's room in aluminum foil, then planting alarm clocks in all the ceilings, then three computers hidden in different places around the school synchronized to play "What Time Is It" from High School Musical through really loud speakers went off about fifteen minutes before school ended.

Forget me not on May 22, 2011:

One year at my sisters highschool the senoirs got 2 goats and put signs on each one. One said "1" and the other said "3" ALL day the faculty was out looking for goat number2 only to later find out there was none (:

Rosalyn on May 15, 2011:

Reprogram all the school's phones so that they forward to your teacher's phone! epic results.

Ellis 2012 on May 12, 2011:

okay, they all sound like great pranks but how about the classic "Three Little Piggies" prank. you get to pigs and write one on one pig then write 3 on the otheer pig and let them loose. when they find the pigs they think that theres 3 and they start thinking that they need to find number 2.

warrior tomboy! on May 05, 2011:

I took mud and covered all the cars with mud. And I spray painted the windows black and blue on the main building.

Ry ry on April 22, 2011:

Haha last year a bunch of seniors put like 4hawks in the bathroom

??? on April 22, 2011:

where can someone get that much hay?

sicp2012 on April 17, 2011:

-drop a box of ping-pong balls down a staircase. during a passing period

-expanding foam in all of the stalls...nd urinals

- block the door with expanding foam

-middle of the night brick off the door as in put up a brick wall in front of the door

-run a piece of wire across the the bottom, like a tripwire

-use saran wrap or streatch tight over toilets and doors

sorry for horrible spelling but whatever

b-man on April 05, 2011:

my senior year so far:

- kill grass on football field in shape

of dick during homecoming week

- moon senior photo

- crash homecoming parade with my truck

in the parade (classic)

- streak baseball game

SENIOR on March 31, 2011:

We are getting ready to pull our senior prank and its gonna be awesome! We've got pretty much every senior participating. Were pretty much going to pull an all nighter together then get to school super early, but everyone with trucks are going to come with haybells in the beds of there trucks then all seniors will park in one parking space and then we're going to fill the rest with the hay. Then after everyone starts to arrive we are going to have water ballon fights and a BBQ. This works better if you have a super small school like this with a small parking lot... its gonna be pretty epic

HelenthalArmy27 on March 31, 2011:

Thank you for the ideas! My fellow graduates and I plan on doing many of these throughout the year. Many great ideas!

Decent prank on February 23, 2011:

2 years ago our senior class had a pretty good one. They had a ton of people ride scooters, bikes, and skateboards through the halls while yelling and causing chaos. They called it "Tour de Century" (Century is our school's name). But they ended up all getting suspened for the last 10 days of school, which was total bs cause it was awesome and didn't do any damage. Anyway, that's a good prank and it's pretty easy to pull off too.

Sparkman High School on February 22, 2011:

Ok, so ive read all the comments you all have wrote and ive seen a bunch of good ones. Ive also seen a bunch of bad ones too. So check it: Im going to put glitter in the AC units, write 2011 on all the 1st story windows, salt the grass, and roll the trees. Oh and last but not leist baby oil the bathrooms! 2011 Sparkman High Huntsville, Alabama.

2015 on February 07, 2011:

LOLZ

Layla on February 01, 2011:

At my school Our grad prank last year was fill a inflateable girl up with helium and send it to the roof of the student centre, and then we had a huge water balloon fight.

steven on January 22, 2011:

i'm going to try to find a way to connect the bathroom vent to the principle's office, so that way every time someone takes a shit he gets to smell it.

Katiee on December 11, 2010:

Dear Mikey, your brilliant. Do you have any idea how long it would take to superglue the 4,500 lockers in my school? Not to mention how much superglue it would take? And your school would probably go bankrupt having to buy new lockers. Have fun with that.

Wolf3 on November 30, 2010:

Our class used window glass marker and wrote our year on every single window in the school. We also Tp'd the trees and cautioned taped the the parking lots. SENIOR PRANKS MAKE HIGH SCHOOL FUN!

C/O 2013 on November 30, 2010:

I have a few good pranks.

1) Have a bunch of people come to school the night before. Get a bunch of chocolate bars. Smear them everywhere, so they look like poop. Make sure that's what people think it is. Then have someone go up to one of the smearings, wipe it off and lick it.

2) If your school has those easy to remove or slide ceilings, put a bunch of alarm clocks in each room in the ceiling and set each one to go off at the same time.

3) Your school should have an additional bell system, in case for days when u have to get out early and such. On a regular scheduled day, find a way to hack into the bell system and change it to the other one. Everyone will be so confused.

4) Usually seniors have jobs in the office, usually the announcements. Make a list of funny names for them to call up like "Mike Hawk" or "Icebank MiceElf".

5) If you're school is major rivals with a different school, do something that has to do with their school. For example: put stickers of your mascot all over their school.

6) Usually schools have letters to give out to students when there are projects. If you have some type of biology teacher that u hate, this prank is perfect. Make a copy an hand them out to every student in your class. This is extremely helpful if you have a class helper. In the letter, state that the project is gonna be about studying roadkill and that the students will have to bring in some. Set up a student-teacher conference and have the kids get their parents to bring in se roadkill.

7) If your school doesn't have a pool, this is perfect. We do thi every year to the incoming Freshman. We tell them how there is a swimming pool that's held under the gym. At one random day, we put out posters of an after-school event of the gym-swim. Its even perfect to set the day of the gym-swim if you have "beach day" during homecoming week.

If I have anymore ideas I'll be happy to share. Peace out xD

jrsmithva on November 29, 2010:

im planning on duck tapeing the whole front way into my school and feeling the inside if it with ballons class of 2011 baby

THE on November 01, 2010:

Okay, people... read the comments that have already been made. There's like 10 people who already talked about the "1,2,4 pig prank" and the supergluing lock prank.

Mikey on October 30, 2010:

N/A on October 23, 2010:

DogHog on October 21, 2010:

To add to the Pig prank where you number three pigs 1,2,4 get a soundtrack or record a pig and then play the record at random places in the school so they will have added proof that there is one there especially when there isn't, also it is really fun to put a recording of some weird sound outside the principals office, or the staff lounge

kyle Oldham on October 21, 2010:

hehe, i am graduating this year class of 2011. and i have already done 2 pranks and its not october 21.

indierokker on October 20, 2010:

I like the ideas where you either throw thousands of bouncy balls down stairs, put a slip 'n' slide in the main hallway, or oil EVERYTHING!!!

Lion on October 13, 2010:

We put a range rover in the library last year...It was fantastic.

Alex T. on October 12, 2010:

My prank was the best the school has ever seen. So my principle says. we filled more than 700 plastic cups with water and willed the whole main staircase, Criscoed all the locker knobs and door handles, blocked the bus loading zone with hay bales, scattered copies of CLASS OF 2010, T.P.ed the whole school.... on the inside..., and shoe polished the windows and vending machines. Me and my buddies that thought up this plan where mentioned in every speech during our graduation ceremony for our constant pranks throughout our high school career. I will never forget how awesome high school was. !!!!!GO MYRTLE POINT!!!!! Alex.T

JON12345 on October 11, 2010:

okay, so i love the idea of 3 chickens with numbers 1,2, and 4 painted on them

so im going to take this a step further.

a few days after the first chicken prank, im gonna put a chicken with 3 painted on it in the principles office.

2013!!!! And A NEW SCHOOL MVHS!!!!! on October 09, 2010:

Brand new school and 2013 is going to be the 1st graduating class... workin a BIG plan for the first senior year ever!!! need the best one to set a rep. for our new school! everyone will remember it! So pumped!

sawyer highfill on October 07, 2010:

me and three of my friends went to our rial high school the page pirates, and they had a huge satue of a pirate in front of their school. So we took a chain saw and an axe and cut it off. then when we played them in football we hung it on our goal post.

=) on September 29, 2010:

Our school has a rule where you have to turn in your cell phones into the office at the beginning of the day if you bring them. Nobody ever turns there cell phones in! So this year we had the senior class get together and set our phones on the counter in the office and just walk out! Well the office paid us back at the end of the day because everyone had to stand in single file to wait for their phone. As you could imagine, this took quite some time!

rg on September 26, 2010:

ok, for 'Alt358 is gay' and anyone else who suggested it, putting glue in locker or door locks is one of the stupidest pranks you can do and it costs a lot of money just to fix them all. i'm all in for senior pranks, and i'm trying to plan one now, but vandalism and the destruction of school property are HUGE no's. pranks should be in good humor, like most of the other pranks mentioned here, but gluing locks just isn't cool.

just find a different prank people, and thanks for all the suggestions, they're really cool! 2011 forever!!!

2012!!! on September 16, 2010:

Spray paint your class year on an old mattress then put it in the schools pool, mattresses are HEAVY when soaked, like the administration will have to get a crane!!!

2012 on September 15, 2010:

putting cling film on the toilet seat is hilarious

SD WOLFPACK on September 11, 2010:

Just made a huge grad 2011 sign in fertilizer on the field. Hope it works!

Alt358 is gay on September 09, 2010:

Okay alt358 what u said was the stupidist thing I have ever herd. "wait I forgot what I was going to say" u are an idot. But a good prank is to buy some glue from a hardware store and put it in the locks so they can't open the doors and u bassically get to miss school. It's pretty legit

2011grad on September 08, 2010:

me and some friends of mine considered putting duct tape on all the lockers like 5 inches thick so that when all the students tried to get into their lockers they wouldn't be able to with going all the way down the hall to pull the tape off

Nuzzys on September 01, 2010:

I put really weak laxitives in the mashed potatoes during lunch, and locked the doors to every bathroom in the school except one. It was funny seeing the line of people at the one bathroom. on August 27, 2010:

man i love a lot of these but the only thing is its gonna be hard to do some cause my high school is brand new this year so in two more years when we're the first graduating class i wonder if their going to let us do pranks but me and my friends are cool with the principals so i think we can talk to them about it. LETS GO 2013!! ALL DAY BABY ALL DAY

alt358 on August 23, 2010:

hey i need some ideas on how to dismantle a car then put it back together. also how did u all get it in the school? pick the locks or help from a cool teacher? also.......i forgot what i was going to say.....oohh now i remember like ill get a friends parents car (with the parents permisson) then when they go to set up the graduation have the parent come in all pissed like hey what the F*** is my car doing here?? the princealbe will be like sir/mam i dont kno we are trying to figure out... well i dont know how it got here or who put it here but i want it out now! and i want the school to do it not the janitors (because they have a hard enough job) but you or (which ever teacher((s)) you dont like) should be funny as hell also im in 8th grade. and i have yet to plan for senoir graduation. on August 13, 2010:

Haha good pranks I enjoyed reading them all. Class of 2012 SHAUUUU!

north canyon pranks on August 05, 2010:

eb97 on August 02, 2010:

if your school has a swimming pool and you have to take aquatics, you should gather a snapping turtle or two along with some frogs and let them go early in the morning before the classes would come into the pool area. the turtles and frogs would be ok for a few hours, just leave some kinda note or something so no one hops into the pool and gets bit by a snapper. that shit hurts

ltdltd on July 28, 2010:

just thought of a good one. hang tons of aluminum cans from the ceiling in every grade designated hallway(fresman, sophmore, juinor)

Hebron hawkkk on July 26, 2010:

These past two years a freshman center was being built in what used to be our student parking lot so we had to move to one on a hill above the teacher's lot. They also built a fence so that we have to walk all the way around it to get to the school. Last year they inserted speed bumps into this new lot as students tend to drive recklessly.. These bumps were cheap mountains anchored down by heavy duty screws and everyone hated them. (there was a Facebook group dedicated to hating them as well lol) The senior prank was to remove these bumps by simply unscrewing them. They got half of them done and intended to do the other half another night before camping out in the parking lot but they were caught and got in some trouble for "trespassing." idk if they got in trouble for removing the first speed bumps but it was an epic prank regardless. Me being a junior appreciated the lack of HUGE speed bumps :]

JJ101news on July 22, 2010:

id luv 2 do one it sounds lk fun but i dont wnt 2 get in trouble and stuff lol plus me and my class aren't tht very close so CLASS of 2011 world wide better rock all pranks this yr lol

My grad class was this year and we managed to get the key for the auto shop and the gate to the field, we then dug a hole at 2 in the morning and buried the car in it. Tomorrow we are going to capture about 5-10 seagulls and let them loose in the main entrance its going to be amazing

last year the seniors tied striong to all the lockers that were across the hall from each it made it hard to find a way through all the strings to get to class =D

Im writing an article for our school newspaper about school pranks, this year the seniors spray painted 2010 ALLOVER, you can still see it in the courtyard and trashcans and some arches, as well as the elevator and staircases (our overseas school is kinda gehto, but its soooo fun at our school) and its rumer a couple people took apart a car and put it back together in the gym.

for our senior prank we r planning on having a pool party, people show up in bathing suits to school, theres mini kidi pools and slip n slides all over the hallways, we all wear sunglasses and pretend to be tanning on the staircases. IDk these sound pretty good though!!!We also might use the teachers parking lot as a " Used cars for sale" and tie ballons to the cars and put posters all over them. A couple of my friends already prank some of the cool teachers. We gummie beared a teachers car and put cold water on it in the winter, so the gummmies froze! LOL we also shaving creamed the desks in another teachers room. You can also team up with a friend and during a class where the teacher wont let u leave, tell them u have to pee really bad, make a big deal of it,if they dont let u go, wiat about 5 min, then under the desk pour water on you croch/leg, and have ur friend scream or laugh... Funniest thing of my life! lol

The seniors this year had a master key to all the lockers and since we have to have a lock on our locker they switched all the locks around and we couldn't get into our lockers.

classof2013 on May 26, 2010:

hellz yeah every1sfavrebel, go class of 2013!!! Me & my friends were planning on buying like hundreds & hundreds of little bouncy balls, then lining up on the hallway that's above our school's commons area and just whipping all of them down onto the people in the commons lol :) plus we're all gonna come to school with our swimsuits on under our clothes & start running through the halls and stripping down to our swim suits & then run & jump into the pool!!! Only 3 more years...can't wait!!! :) It's gonna be way better than this year...all they did was put babyoil in one hallway, 2 people dressed up as a banana & gorilla & ran through the school (that was pretty funny lol), & they put post-it-notes all over the commons....but the class of 2013 is gonna make history!!

every1sfavrebel on May 26, 2010:

my senior prank is gonna be huge! we r gonna get the choir kids to all break out into song and dance during lunch or during class while that's happening we r gonna have other distractions going on so all the teachers get detracted. while that's happening all the rest of the seniors r gonna do something big but we r still deciding on what the will be. 3 yrs to figure it out GO CLASS OF 2013!!

at our school the got three chickens and painted numbers 1 2 &4 so all day they were trying to look for pig number 3 but it was never there

Interested Party on May 19, 2010:

My favorite from my high school was when a class literally built a 10' high wall across the access road to the school. They built the cinder block wall overnight, so the next day people couldn't drive up to the main doors of the school.

Stuff on May 18, 2010:

Qwerty, how about unroll all the toilet paper, and leave the empty roll there, then write, ha ur screwed, on them. xD

canola oil, all over the halls and classrooms.

Fishing line, at the student entrances so they all trip

Ask a freshman or two to help you with senior prank, than duct tape them to the pillars outside your school.

Used tires in all the parking lots

desks in the hallways

sticky notes ALL OVER

3/4 pigs


Doing something to the principle, something he/she hates very much (mine hates whistles)


Saran wrap the lunch room


That's all I got. Peace =)

I saw a video like this, but get a couple of people to dress up as bananas and a couple of people to dress up as gorillas and gave the gorrilas chase the bananas around the school screaming

That's probably not a good idea, as it can be quite pricey to correct broken pipes, and depending on the school, if the pipes are old, they'll break easily. You don't want to get in trouble for vandalizing.

kenny c on May 07, 2010:

i love these ideas, we were thinkin of clogging all the drains in the sinks and water fountains and turning them onn to flood the schoooool
