What Was Banned In Your School Because Of Some Crazy Incident?

I went to Lancaster High School where during my high school career some of the weirdest things were banned. Going down the laundry shoot and bouncy balls were a couple of them I can remember.

The laundry shoot.

You would think you didn't have to tell people to go down a laundry shoot, right? Not until someone finally cracked their head open were warnings sent out.

Bouncy balls.

The bouncy balls? During a Senior Prank, someone threw thousands of bouncy balls down a flight of stairs in between periods that made it dangerous (yet amusing) to everyone walking around.

How about this one below? Students are banned from wearing yoga pants, but not because of any one incident--they're causing a distraction.
