The guy also takes an old lady's car while she is in it, so he puts her head in the moon roof and closes it so her head is sticking out. She starts screaming and the lady driver in the car in front says "It sounds like the police I better pull over."

He also either has a testicle transplant or he sells one of his testicles.
