The 19 most successful senior pranks in the history of senior pranking.

The 19 most successful senior pranks in the history of senior pranking.

Senior pranks are a timelessly fun practice beloved by teens and dreaded by custodians. It's students' final chance to make their teachers regret becoming teachers. The best kind involve hijinx that inconvenience, but only right up until before the point of doing any permanent physical or emotional damage. Below are high school seniors who perfected the craft, and almost surely put more effort into their feats of mischief than any of their school work.

1. The kids at Boyertown High may not have left school with a sense of maturity, but at least they have landscaping experience.

2. It was a very bad day to be on Staley High School's janitorial team.

3. The class of 1985 at redditor u/_ISON_'s school had a prank that seems to have never ended.

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.

4. Most of these schools did not fetch a high resale value from the students who put them up for sale.


5. Redditor u/ctrm5336's senior class managed to prank two schools with one gag.

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.


6. You can never go wrong with thousands and thousands balloons.

7. So harmless, so dumb. This friend of redditor u/frisbeefrank's is a visionary.

My friend attached an F to the art room sign so it said Fart Room.

8. Making their coach think he's getting arrested definitely earned these kids a few extra laps at practice.

9. Honestly, flunking out of high school for having an "unorderly penis" would be kind of cool.

In honor of our senior prank happening a year ago I thought I'd do a throwback 😌

10. According to redditor u/therealmax, 'going out with a bang' is just a synonym for 'fly into the Danger Zone.'

Rode through the halls on my razor scooter wearing nothing but aviators, cowboy boots, and my tighty whities while the top gun theme song was being blared through the intercom. A few minutes later I was tackled by my principal broke free left my scooter behind and sprinted out of the building. I got one day of I.S.S. and my parents had to go get my scooter and hear from the principal why it had been confiscated.


11. The seniors at Raymore-Peculiar High School honored their final Hump Day together by renting the most hump-appropriate animal possible.

Yep. This is raypec'a senior prank. Good one. #lame#seniorprank#camel

12. The class above u/bananaboy23 disappeared the teacher's lounge, likely inciting dozens of coffee withdrawals that day.

The class above me had the best prank I have seen. They removed the door moulding of the staff room, and dry walled over the current door. Painted it, touched it up, making it look like part of the wall. To top it all off they bought a plant and placed it in front of where the door should have been. It was hilarious watching the teachers walk past and do a double take as they looked for the non-existent door.


13. This school's secretary is doing a very good job pretending she's not nearly up to her neck in packaging peanuts.

14. At redditor u/scotscott's school, you never know when a dildo may fall in your chowder, and that is not an innuendo.

a previous class had hidden dildos all over the school. Every so often we'd find a random dildo even a few years later. One day, we had the windows open in the dining hall, were eating lunch, and a strong gust blew by. An overlooked dildo was on one of the rafters and it fell down and hit someone in the head. new england clam chowder splashed everywhere.

15. Formerly known as Lannister Central.​


16. No matter what possessed u/BrushedYourTeethYet to do this insane 'Where's Waldo'-inspired prank, he was on to something. It worked beautifully.

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.

Extra info on the prank in case you want to execute it yourself:

-my year coordinators office was in a specific block within the school, so I made sure to hide the posters away from that area but still in areas many kids would be. E.g near the library, oval, or a toilet block etc.

-the day after the prank, I put up more posters thanking the school for participating in the grade 12 prank, and left a personal note for my year coordinator thanking her for being a good sport about it (taped to her office door). You know, just to rub it in a bit.

-I think I only did about 5 posters so I could make it relatively easy for kids to find them all, just so I could maximize the amount of kids flooding to my teacher's office.


17. These principals better have left a tip for the mariachi bands who their students hired to follow them all day.

18. Bringing dozens of dogs to school isn't even a prank, it's just what everyone wants all the time.


19. Lastly, u/jitzkrieg revealed that the best prank of all is actually no prank. Simply the ominous threat of one will do.

Operation Catfish.

Weeks of hushed conversations. Rumors spread. Administration got wind of it. Started asking questions. "What is Operation Catfish? When will it take place? Who is responsible?" No one broke. This was to be the greatest prank in the history of the county.

The day came. The plans were set. Teachers posted throughout the halls like sentries.

Nothing happened.

We catfish'd 'em.
