I once walked into the bathroom in high school to find one of the guys from the special ed class (a tall, large black guy who was always laughing) standing in there just laughing his ass off, and as I walked up to the urinals noticed that the stall he was standing in had a huge pile of green shit sitting on the rim of the bowl and smearing down the outside. And he was just laughing his ass off about it like a villainous, retarded mastermind.
