Two young men are holding an engine in the air while an old man is working beneath it. One of the men lets go and the engine crushes the old man. The detective comes and asks the young man, “What do you know about the victim?”
“He was an old man,” the kid says.
The detective says, “I can see that. You don’t know anything else?”
The man shrugs and says, “He had two buttholes.”
The detective yells, “You jerk! This could be murder.”
The young man says, “Well, every time the three of us went to the bar down the street, the bartender would say ‘Here comes that old man with the two buttholes.'”
