A midgit walks into a bar and promptly slips on a piece of shit and lands on his back. Embarassed and hoping that it went unnoticed, he proceeds to climb onto a barstool and order a drink.

A good while later a large man walks in and proceeds to slip on the same piece of shit that the midget encountered earlier. Noticing this, the midgit, putting on his friendliest smile laughed, "Yeah, I just did that!."

So the man killed him.
