A man is sitting at the bar in a crowded pub when he notices a man at the door.
The man at the door climbs up the door post walks across the ceiling above the throng and climbs down a post by the bar.
He orders a pint of lager, knocks it back and climbs back up the post exiting across the ceiling the way he came in.
The man at the bar turns to the bartender astounded and says “Now that's unusual isn't it!?”, the bar tender replies “Yeah, he usually drinks bitter”
