This man comes through a door to the bar and slipped on a pile of crap, he mumbles and brushes himself off.
He orders a drink and sits down. A few minutes later a younger man walks through the door yelling and screaming, and he slips on the pile of crap.
He gets up and looks around, and then he sits down next to the older guy.
The older man says, "I did that!"
The younger man punches the old man and leaves.
