US High Schoolers of Reddit, what are some of the most bizzare things you have found in the restrooms?

I didn’t find it but.. when I was in high school one of the buildings I had classes in was condemned for renovation because a girl threw a hot crack pipe away in the bathroom trash and started a fire burning down about a third of the 2 story building

I was going in to piss and like two guys blowing each other in stall and I walked right out

Former highschooler here. I walked into our restroom in the cafeteria and a guy was jacking off in the stall
