Two monkeys walk into a bar and order a couple of beers. The barman had
never served monkeys before so he was a little taken aback. He decides to
consult with his manager, so runs up to the upper office to speak with
Ian.
"Ian! There are two monkeys downstairs ordering beers! What do I do?".
Ian: "Serve them you idiot. Oh, but wait: monkeys are stupid, so charge
them twice the price. They won't know the difference."
The barman goes back down to the bar, serves up the beer, and charges the
monkeys double. Later in the evening, the monkeys are still nursing the
same beers while the barman's tidying up. Curious about these furry visitors,
the barman comments: "Say, we don't get a lot of monkeys around here...".
The monkeys look at each other and then back at the barman.
Monkeys: "Well, with prices like these, no wonder!"
