So this guy thought he was funny by pissing on the floor and not in the urinal.
Later on, I guess some kid ran into the bathroom because, well, he probably had to go, but yeah, he slipped and fell and hit his head on the urinal, so all in all it was a pretty good prank on his part.
Listen up, dummy! So, this dude peed all over the bathroom floor instead of using the urinal like a normal person. Then, some poor kid runs in, slips on the pee, and whacks his head on the urinal. It's funny because it's a stupid prank that actually hurt someone. You wouldn't get it, though, since you are probably the kid who slipped.
