A little fella walks into a bar.

Unfortunately there is a pile of dog shit 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.

A great big man then enters the bar.

He slips in the same pile of shit, falls, gets up, cleans up and buys a drink.

The little guy turns to the big guy and, trying to strike up a conversation, points to the pile by the door and says, "I just did that."

The big guy punched him in the mouth.
