A gorilla walks into a bar and, to the amazement of the bartender, orders a martini. When the bartender gives the gorilla the martini, he is further surprised to see that the ape is holding a $20 bill.
The bartender takes the $20 bill, then he decides to see just how smart the gorilla is, so he hands the gorilla $1 change. The gorilla quietly sips the martini until the bartender breaks the silence.
"We don't get too many apes in here," he says.
The gorilla replies, "At $19 a drink, I'm not surprised."
