School pranks

[TheImportantFart]

This is a thread for sharing pranks at school. They can be ones you pulled, ones you witnessed, ones you heard about, ones you were a victim of, ones that were performed against fellow students, teachers or the whole school. As long as it happened in school (or any educational institution) it's fair game.

I'll kick us off with a couple.

The Alarm

My secondary school was near a mental hospital housing some extremely dangerous inmates (we're talking serial killers and the like). The hospital had an alarm to warn if one of the inmates had escaped. The alarm would be sounded every week at the same time on the same day as a drill. We were told that if we heard the alarm at any other time it meant one of the inmates had escaped and we needed to be on alert.

One day, some guys who were in their final year thought they'd go out in a blaze of glory by recording the alarm and playing it at full volume into the main quad of the school. My school was a boarding school and they chose to do it just as everyone was about to go to bed causing absolute chaos. I wasn't in the main quad so I never experienced it first hand but people who did said everyone instantly went into panic mode and started running round like headless chickens.

It was discovered fairly quickly it was a and the guys who did it should've been in serious trouble but they were in their final year so no-one could be bothered to expel them and they pretty much got away with it.

A watched pot is never soiled

Every boarding house at my school had its own kitchen with a toaster, microwave, kettle and stove for preparing rudimentary meals and snacks. In one of these houses, someone took it upon themselves to brighten up everyone's break time by taking a piss in the kettle. Somebody else came in to brew some tea and switched on the kettle.

Naturally, the piss evaporated after being boiled and for months afterwards the kitchen stank of it.

I've got plenty more stories to tell but I wanna hear some other people weigh in first.

I was in math class and this mother fucker leaves the room, comes back with a cookie and gives it to me, I eat it and he tells me he found it under the lockers.

I get a forever alone sign taped to my back and someone takes a picture of me in history class with it on my back and it goes on the internet. I honestly thought it was pretty funny

We do a science experiment with fish (learning about eco systems) and after it's done a bunch of dude bros start daring each other to eat the fish for money. Of course I put a stop to it and take all the guppies home to live in my tank where they spent several years.

Also I got dared to eat a shit ton of fish food, a ghost pepper and to stick my tounge in a toy plane propeller. I do all of these things because I ain't no pussy

Edit: here is forever alone me

It got on tumblr and people from the school were reblogging it and saying "oh my God that's so mean" and then I chimed in and I'm like, that's my back and that's hilarious

At the end of my senior year of high school, I joined a bunch of other graduating band members in camping out on our band director's lawn. The funniest part is that when we got to his house after midnight, he was still awake, so we went to Dunkin' Donuts to pass some time.

 

[Hyperion]

Last day of school junior year of HS myself and a few buddies got an assload of water balloons and hid in the bed of another guys truck. We cruised by the people getting onto the buses and ambushed them.

Amazingly we didn't get arrested and charged with terrorism. We never even got in trouble for it.

 

[Coffee Overdose]

oh man do I have a few for you.. LETS GO

---------------------- THE CHICKEN
We released a chicken in the school cafeteria. It was hilarious watching a few teachers and a principal chasing it around trying to grab it or capture it. It was great watching them do that. Quite hilarious.

--------------------- THE CAR HEIST
A few friends of mine decided it would be a good idea for the talent show to take apart the principal's car and put it back together.. on stage. No one was arrested because they were literally stunned over how fast they took the car apart (45 minutes during lunch time, and 15 minutes during the talent show). They ran off stage after putting it back together. No one was punished.

-------------------- THE BREAK IN
Our school had a busted lock. The door to the side wouldn't lock completely. A quick jiggle of the handle could easily open it. My friends and I one day at 2am decided to go inside. One friend and I messed with lockers, teacher's desks, papers, etc. Nothing big.

Our other friend came down the stairs running. Laughing, grinning like crazy. All he said is "We gotta go, We gotta go." and then we all ran out. The next day there was a rancid smell in the school. Didn't know what it was. My friend was smiling greatly. Just a huge ass grin. An announcement came on. "Because of vandalism our school day will be halved. Please contact your parents about the changes" We go upstairs to the freshmen hallways.. there is pee EVERYWHERE. Just everywhere. Pure 100% piss. Completely covered lockers, rooms, and everything. Our only thought "How did you generate enough piss to cover the freshmen hallways?"


I have more and I'll post them later.

My idea for a senior prank involved random broadcasts on the school PA system every few minutes. The ruse that was supposed to keep the prank going was all people involved in the prank were to be in the photography room. Besides the door being locked, the prank would take place during a darkroom session when no school administrator would dare interrupt.

Another classmate had a competing idea, he was going to erase all the computer data off the photography server.

For one reason or another, these ideas did not come to fruition. Instead the real senior prank was held graduation day. It was held at the last minute and i reeked of last minute effort. The prank centred around various glowstick objects being passed out to the seniors. When a graduate came up, they would give the principal the glow item. Eventually the principal would be covered in glowsticks.

A kid asked a teacher if he was a virgin in one of my highschool classes, which is a pretty low effort shit prank. What made it insanely hilarious is that the teacher went to the bathroom directly across the hall, and audibly cried for about 10 minutes. I do believe the kid who did it is a fellow kiwi these days as well. In retrospect, I feel bad for the guy but as a freshmen it was comedy gold.

I'll have to post this later when I'm not as tired, and it's less of a prank and more of a "Psychology profs are fucking weird," but fun fact: apparently wild turkeys have really good memories, and also attack people they recognize from bad memories.

A couple malicious things a few buddies and I pulled come to mind. This was back in 1999 so I don't recall if laser computer mice existed back then, but our computers in the lab had those kind where the ball inside and underneath the mouse moved the cursor. We took those out of every mouse and I forget what we did with them, but they weren't returned. And in that same week, something I didn't partake in but kind of encouraged was when a friend of mine flushed a bunch of finishing nails from shop class into a urinal. I felt bad about the fallout from that one because the janitors, who were cool as fuck, had a hell of a time cleaning them out of the pipes.

That week, they held an assembly in the gym and both of these incidents were brought up. Us guilty bastards sat through it trying not to laugh and luckily, we never got caught.

Couple more from me:

Teacher's footsteps

We had a teacher who... let's just say was a little slow. He was actually a really bad teacher because rather than teaching the class he'd go on long, rambling tangents on unrelated subjects that weren't even interesting. His class were on track to get terrible exam grades until another teacher intervened and picked up the slack.

Anyway, since his students realised they weren't going to learn anything from him they thought they'd mess with him instead. So in his classes, every time he turned around to write something on the board, the two people at the front desk (we had shared desks in the classroom) would inch the desk forward ever so slightly. They'd keep doing this until they were right behind him, effectively trapping him between the desk and the board and only then did he tell them to move the desk back. They did as they were told... and then started over again. And they never ever got punished for it

Skiving contest

We had another teacher who was much better at teaching but still a bit clueless when it came to certain things. We began to notice that when people left the classroom to go to the toilet or what have you, in some cases she'd ask where they were after they'd been gone a minute or two but in other cases she'd forget about them even if they'd been gone twenty minutes.

Anyway, some folks took advantage of this and decided to hold a contest to see how long they could stay out of the classroom without being detected. The record was set by a guy who asked to go to the toilet, didn't return for 45 minutes (lessons typically lasted an hour) and was never questioned on his absence.

Eventually, staying out of the classroom for as long as you could was deemed not "extreme" enough so it was changed to seeing how far you could get away from the classroom without being caught. You also had to bring something back from the place you'd reached to prove you'd been there. For a long time, the record was the Sports Hall (my school was huge and the Sports Hall was at least a 10 minute walk from the classroom) but that record was eventually broken by the same guy who set the last one. He managed to reach the train station in the town where my school was and brought back a train ticket to prove he'd been there.

Hardcore necropost but:

Tape on the teacher's computer mouse's laser. Nothing better exists

 

[Tragi-Chan]

One time some guys at my school painted an enormous penis on the playground with masonry paint with the words “SCHOOL’S OUT” underneath. In the end, the school had to pave over it.

 

[LazarusOwenhart]

My high school banned Amy image or reference to Super Mario on school grounds because we had a teacher called Mr Macarthy who was the spitting image of him and was also a softhearted older man who took things a little too personally. I think one too many people yelled "It's a me, Macartheyo!" In a corridor and the head decided banning the plumber was the way to stop it.

 

[NIGGER ASS PEE POOPY RAPE]

in high school after lunch I took ziplock sandwich bags that mom packed my sandwiches in and went to the bathroom and shit on the floor and picked up the shit with the sandwich bag and smeared it everywhere, especially in the most hard-to-reach places I could possibly find to make the janitors' lives hell. I smeared shit behind toilets, inside hand dryers, inside soap dispensers, climbed on the toilet to smear it on the ceiling, etc. and then flushed the sandwich bag down the toilet which I'm pretty sure clogged the toilets a few times. I also pissed all over the floor and filled the toilets with entire rolls of toilet paper. I did this dozens and dozens of times and never got caught.

the hardest part of covering up my crimes was trying not to laugh too hard in the next class or when seeing a janitor's face after he just had to clean it up. a couple times in class I had to explain why I was uncontrollably laughing so hard about seemingly nothing and had to make up an excuse like "I was just thinking of this hilarious thing I saw on TV last night" which made me sound like a tard but it was worth it. each janitor lasted an average of about two shit clean-ups before quitting. one time I even heard that some dumbass fat kid actually slipped and fell in my piss and had to go home because his clothes were soaked in my piss.

 

[The Pink Panther]

In 6th grade, I put a bunch of slices of bananas on the steps to the second floor during lunch. Not banana peels, bananas. I figured that the inside of a banana is somehow more slippery than the banana. I somehow never got caught and apparently there was so much chaos on the steps, quite a few people got detention for the ruckus.

 

[The Last Stand]

We had a food fight when several of the teachers were away on a conference. We got yelled at for several periods.

Some of these might be repeats from "Share your school stories" but still worth it for the topic.

Grade School
In fourth grade, a classmate put a bang snap on my chair while I was standing or away from my desk. It never banged and I wondered why I suddenly had a white stain on my pants that wasn't there before. To nobody's real surprise, it was later revealed that the culprit was one of the class troublemakers. I'm not sure if it was bravado, stupidity, or some of both that had him do this in a class taught by a nun who had a reputation for being strict. While the rumors about her strictness were largely exaggerated and unfounded, she had no qualms disciplining anyone who seriously misbehaved. One such example was the time she actually entered the boys bathroom to remove this same troublemaker after he urinated in the trash can instead of one of the toilets or urinals.

High School
My freshman year of high school, a weirdo from one of my classes tried to prank me by looking up my family in the phone book and calling. When I answered the phone, he tried passing himself off as my principal and claimed I was being suspended. Too bad for him, he didn't come close to sounding like our deep-voiced principal.

Another freshman year incident ended up being a prank when it wasn't supposed to be. One of the few educational assignments in my Survey of the Social World class was to come up with a product and some sort of brief jingle or commercial promoting it. I decided to do one for bug spray and started my commercial by looking in the trash can and saying something like, "Eww! Roaches!" As soon as I said that, the entire class took me seriously and a number of my classmates ran up to the trash can to look at/for the roaches. They seemed disappointed to learn there weren't actually roaches in the trash and that it was just the first line of my commercial. My teacher seemed amused enough by the whole thing to give me an easy A.

Finally in my freshman year, some guys pranked our homeroom teacher into calling one of the girls, "Curly." At the time it happened, I had no idea WTF they were talking about, but I later learned it was supposedly an underhanded reference to a girl having pubic hair. That would explain the girl's visible embarrassment over it.

My junior year, I used a utility found on the Macs in my imaginative writing classroom to tell someone in the next room over her computer was acting up when it really wasn't. Despite finding it immature, we became friends until she graduated later that year.

Roughly half of my American Government class from my junior year apparently pranked our teacher and I had no idea it happened until someone discussed it outside of class. Our teacher, someone I'll call Mrs. X, apparently had hearing issues because she wore hearing aids normally hidden by her hairdo. It only became obvious she had hearing aids when she had to manually adjust them once during class. One day, the students on the opposite side of the class from me decided to speak in gradually lower voices until Mrs. X adjusted her hearing aids. Once she did, they spoke at normal volume until Mrs. X had to quickly adjust the level again.

My senior year, a classmate tried to prank me by having another girl (possibly his girl friend) write a letter claiming to be from my crush that year. The fact the note used language said crush would never use with me was the giveaway the note was fake. I returned the favor by typing up my own fake sultry love note purportedly sent to him from his girl friend. He wasn't impressed upon finding and reading it, but he was graciously willing to call it even and agree to a truce.

Also my senior year, I pranked my physics teacher by writing "911 is a joke" on his overhead transparency with erasable marker. He turned it on, read it out loud, and had no idea what it meant, who wrote it, or why. When someone finally told him it was a song title, he just shrugged and continued his lesson as if nothing happened.

College
My sophomore year, I had a teammate follow me to an off-campus event (either a scrimmage or the team's annual visit to underprivileged children) because I was known for having a good sense of direction. We both had CB radios, so we agreed to use them to stay in touch should he need directions or get lost behind me. On the way back to campus, he asked me to do certain things like use my turn signal or briefly turn my headlights off and back on to be sure he still had me in sight. Once we returned to campus, I learn he had been immediately behind me the whole time and was pranking me for shits and giggles.

 

[Pissmaster]

one time I even heard that some dumbass fat kid actually slipped and fell in my piss and had to go home because his clothes were soaked in my piss.

You make me proud
