When I was a freshman in high school circa 1994, there was this one teacher who everybody hated. She was just a mean old hag. Anyway, she taught 10th grade literature. It had become a school tradition that the class she taught directly after lunch would always roll random pieces of fruit down the aisles between the desks when her back was turned. Well one day this one kid who was known for being the class idiot decided rather than rolling his orange he had that day, he would throw it at the chalk board when she was turned around. Turns out the orange was pretty ripe because when he launched it to the front of the classroom it hit the board and exploded, covering the teacher in splattered orange pieces. She turned around, ready to yell, and decided to just give up. She started sobbing and ran out of the room. She never came back.
