A fella walks into a bar...
Unfortunately, there is a pile of dog poop just inside the door, and he slips in it and falls over. He gets up, cleans himself up and walks to the bar and buys a drink.
Another man then enters the bar. He slips in the same pile of poop, falls, gets up, cleans up and buys a drink.
The first guy turns to the new guy and, trying to strike up a conversation, points to the pile by the door and says, "I just did that."
The big guy punches him in the mouth.
