A man walks into a bar and asks the bartender for a dollar. The bartender says, "Every day you come in here and ask for a dollar. I'll tell you what."

[Dale Cooper Black 340]

But before the bartender can finish his thought, the man shoots the him in the face. Then the man leaves without taking any money from the till. He doesn't even take a dollar from the tip jar or anything. They never do catch the guy, and nobody can figure out what his motives might have been. Crazy world.
