Class Clown
One time in middle school, this guy who was relatively new at our school was making fun of a girl in our class who fell in the hallway in-between classes. Coincidentally, this was a girl I had a crush on. The guy was a little bit of a class clown, and was mocking her, making her look stupid and clumsy. This did not bode well for him.
Apparently, he misjudged his footing, and while attempting to jokingly ape the way she had fallen, actually fell for real, and landed squarely on his back in front of everybody. He broke his arm in the process. Passing him by in the hallway, I saw him just lying there, surrounded by adults and staring up at the ceiling, face completely expressionless. Pretty sure he moved after that. I would have too.
