One day, at the bar...

A gorilla goes into a bar and orders a beer. This totally amazes the bartender, but he thinks, "What the heck, I guess I might as well pour him a pint." He then walks back over to the give it to the gorilla, and the animal is holding out a twenty-dollar bill. Well, now the bartender is just at a loss for words. He can't believe that a gorilla walked into his bar, ordered a beer, and then actually had a twenty-dollar bill to pay for it.

So, in amazement, he takes the twenty and walks to the cash register to make the change. While he's standing in front of the cash register he stops for a second and thinks to himself, "This is a gorilla! What the hell does he know about money? I'm gonna try something here and see if he notices anything."

So he walks back over to the gorilla and hands him a dollar change. The gorilla doesn't say anything; he just sits there drinking the beer. After a few minutes the bartender just can't take it anymore.

"You know," he says to the gorilla, "we don't get too many gorillas in here."

And the gorilla says, "Yeah, at nineteen dollars a beer I'm not surprised."
