A gorilla walks into a bar, pulls out a twenty and asks for a beer. The bartender goes to the tap and while he's pouring he thinks, "This is a gorilla, probably dumb as a banana, I'm gonna short change him. He finishes pouring the beer, brings it over, takes the twenty and puts six dollars and forty cents on the bar. Curious, the bartender says to him, "You know we don't get many gorillas in here."

The gorilla takes a swig and says, At thirteen-sixty a friggin' beer, what do you expect?"
