A gorilla walked into a bar and ordered a Martini. The bartender is amazed, but he thinks, “What the hell.” So he mixes the Martini. As he passes it across the bar the gorilla pays with a twenty pound note. This freaks him out. He can’t believe that a gorilla can walk into his bar, order a Martini, and pay with a twenty pound note.
While he’s standing in front of the cash register he thinks to himself, “Let’s try something here and see if the gorilla notices.”
He hands the gorilla a pound change. The gorilla doesn’t complain. He just sits there sipping the Martini. After a few minutes the bartender just can’t any more.
“You know, we don’t get too many gorillas in here.”
“At nineteen pounds a drink I’m not surprised.”
