Mice on a basketball court, balloons filled with mayonnaise, and more wild stuff.

During the second half of every high school student’s senior year, attention pivots to literally anything but schoolwork. Summer plans are imagined, graduation caps are purchased, and other fun ideas — like senior pranks — finally come to fruition.

If you’re a senior right now, you may be planning the ~*perfect*~ prank that toes the line between epic and worthy of expulsion.

Luckily, Reddit user Waterboyman11 is here to help with some inspiration by creating the subreddit “What was your senior prank?

In less than 24 hours, Reddit users have commented more than 9,000 times, sharing their joys and their sorrows, and for good reason — some of these pranks are killer. ?

Read some of the best pranks below.

  • The 2″ x 3.5″ prank

    “About 30 years ago the senior class bought 10,000 business cards that simply said ’Class of 1985,’ and hid them everywhere. Under couches, behind paintings, in books in the library, in ceiling tiles. Needless to say, the cards are occasionally found even to this day.”

  • The “Eh, Macarena!” prank

    “Played a school wide game of where’s wally.

    I made posters with instructions to find all the wally’s and then report to my year coordinators office to collect the prize. However, I made a condition that you had to do the Macarena to get the prize, and if the teacher didn’t think they were dancing well enough they would ’pretend’ they didn’t know what was going on.

    Lead to a bunch of grade 8 and 9’ers flooding my year coordinators office doing the Macarena as she screamed ’what are you doing? Why is this happening?’ which apparently made them dance with more enthusiasm.

    Year coordinators had to go around the school and find all the posters herself so the dancing would stop.”

  • The quite illegal prank

    “We planned to throw water balloons in the morning as everyone walked in, but the dean threatened to hold diplomas so people just sat on the ground. It was pretty lame. Then some jackass threw a balloon full of mayonnaise at a school bus and obliterated the windshield and got arrested.”

  • The plot of The Holiday prank

    .

    “We swapped senior classes with another local high school for the day. Their entire class was assigned one of us, and each of us were assigned one of them. It was actually a lot of fun, until the electricity blew at our original high school so they all got to go home early.”

  • The realtor prank

    “We listed our school on Craigslist and our principal got calls all day for the property.”

  • The chair prank

    “We combined our senior prank with our senior gift for our band director. We took his old desk chair, brought it up to the top of the 2 story watch tower that he stands on to watch us during marching rehearsals, and threw it off (filming his reaction of course). Then, when he brought us inside to yell at us, boom, there was a new chair sitting at his desk.”

  • The truck prank

    “This was before my time, but a few years before I was in high school the senior class pranked the band director by carrying his truck inside.

    The double exterior doors of the band hall led to a loading dock that was about three feet off the ground. The band director always parked his truck backed into the loading dock. The entire senior class (and probably anyone else they could find to help) lifted the truck up the three feet onto the loading dock and then carried it into the building and put it right in the middle of the room. He then had to get them to carry it back out and off the loading dock because you can’t exactly drive off a three foot cliff in a small Japanese truck.

    After that he bought a bigger, heavier truck to thwart future attempts at this prank.”

  • The ill-advised, probably racist prank

    “A kid in our Facebook group suggested everyone bringing in 2 watermelons, so there would be like 700 water melons lying around the school. As a result, everyone and I mean everyone in our grade brought in 2+ watermelons, so our school was covered with watermelons. Also, our vice principal, who is black, thought that the prank was racist and hateful against him and asked every black kid in the school if the prank was racist.”

  • The inflatable prank

    “Our lunchroom had HUGE ceilings, so a few of my friends on the football team bought a bunch of inflatable sex dolls, filled them with helium and let them loose up there. Nothing like eating lunch to see a wide mouth sexy doll with a huge erection staring down at you with those dead eyes.”

  • The “OMG what’s in that pillowcase?!” prank

    “Someone threw a pillowcase with about 20 mice onto the basketball court during half-time when the cheerleaders were performing.

    This was during the middle of winter and the mice were in someone’s trunk. So they threw the bag and some mice fell out, but even the ones that fell out didn’t move due to being left out in the cold. The principal got to them right away and started picking them up and putting them back in the pillowcase. One of the mice that he picked up bit him and he flung his hand instinctively to get it off and he launched it against the wall. The principal had to get a rabies shot as a result. The week after, many people got called down to the dean’s office for interrogation, myself included.”

  • The long-read prank (It’s totally worth it.)

    “This was not the official prank, but it did happen senior year. The psych teacher, Miss F. was always pointy faced and unfair. She got mad at a few slackers and ended up making herself feel better by giving a pop quiz with the grade on it being a third of our final grade. This brought down quite a few student’s GPA and much rancor ensued. So.

    She also had a doll that sat on her desk. Little Lord Fauntleroy was its name, it had a lacy collar and a wee little hat, short blue pants with suspenders. She introduced it the first day of class, and we all thought her eccentric.

    A few days after the unfair quiz, Little Lord Fauntleroy (LLF) went missing. Miss F. was pissed. She wept, chewed us out, demanded his return. And soon after that came the ransom note. It demanded the results of the quiz be expunged for all and our grades returned to pre-quiz levels. Or LLF would get it.

    The next class the shit really hit the fan … she strode back in forth, crying, demanding we rat out the culprits, and refusing to give in. A few days later a doll ear was sent to her in-school mail box. Wow. She went bonkers.

    This was after the Getty kidnapping and ear slicing event. A note came with the ear repeating the demand. More angry tears. I felt bad for her, but it was also gleeful … she had never been fair and she had openly mocked me as I was clumsy at drawing a pencil through a maze while looking in a mirror.

    Graduation was fast approaching. The last note enclosed a photo of LLF with a black hood on his head, and a noose around his neck. Miss F. caved. He showed up on her desk the next day, both ears on…they must have sliced another doll’s ear. We got our grades back, she had her doll. She retired not many years after that. It remains a mystery who kidnapped LLF, but I take my hat off to who ever it was.”
