A little fella walks into a bar. Unfortunately for him, there is a
pile of dog crap just inside the door and he slips in it and falls
over. He gets up, cleans himself, walks to the bar and buys a drink.

A great big man then enters the bar. He slips in the same pile of poop, falls, gets up, cleans himself and then buys a drink.
Trying to strike up a conversation, the little guy turns to the big
guy, points to the pile by the door and says, "I just did that."

The big guy punched him in the mouth.
