An Englishman walks into a pub with an octopus. He sits the octopus down on a stool and tell everyone in the pub this is a very talented animal. "He can play any musical instrument in the world."
Everyone in the pub laughs, calling him an idiot. So he says that he will bet $50 to anyone who has an instrument that the octopus can't play.
A Welshman walks up with a guitar and sets it beside the octopus. Immediately the octopus picks up the guitar and starts playing better than Segovia. The Welshman pays his $50.
Another Englishman walks up with a trumpet. This time the octopus plays the trumpet better than Miles Davis. This Englishman also pays up his $50.
Then a Scotsman walks up with some bagpipes. He gives them to the octopus who fumbles around with them in a confused fashion for several minutes.
"Ha!" the Scot says, "Can ye nae play it?"
The octopus looks up at him and says, "Play it? I'm going to fuck it as soon as I figure out how to get its pajamas off!
