I remember distinctly that I was in grade four and sitting next to an Japanese guy named Billy. It was in the middle of english when our teacher asked us to "come to the center of the room". Everyone rose up and made there way; except, Billy. He kept sitting there, until the teacher began yelling. When he finally stood up there was a pool of piss on the chair.
That was fucked up. He was sitting in his own piss for over 20 minutes. But hell, atleast I didn't get any on myself.
