We were all in high school once. If you graduated more than 10 years ago, you may have forgotten just how awkward those years are. Between relationship drama, puberty, and stressing about your grades, those four years aren’t really anyone’s favorite time of life.

So, it’s no wonder that graduating seniors feel like celebrating. Not only are they leaving high school behind, but they’re entering adulthood! Now, they can go to college, enter a vocational program, move into their own home, and explore their interests. Plus, they no longer have to sit through P.E.

Of course, as the school year winds down and graduation approaches, things get a little bit more relaxed. And that means it’s the prime opportunity for a prank organized by seniors.

Senior pranks come in all shapes and sizes. There are the classics that include filling offices with balloons, lining hallways with cups of water, and plastic wrapping the principal’s car. There are ambitious ones that include farm animals, bouncy houses, and furniture on the roof. But no matter how big or small the senior prank, it’s all about one thing: making them remember you.

Oh, and causing total chaos, of course. Were these pranks unforgettable or not enough?
