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.
