A guy walks into a bar with an octopus. He sits the octopus down on a stool and tells everyone in the bar that this is a very talented octopus. He can play any musical instrument in the world.

He hears everyone in the crowd laughing at him, calling him an idiot, etc.
So, he says that he will wager $50 to anyone who has an instrument that the octopus can't play.

A guy walks up with a guitar and sits it beside the octopus. The octopus starts playing better than Jimi Hendrix, just rippin' it up. So the man pays his $50.

Another guys walks up with a trumpet. The octopus plays the trumpet better than Dizzie Gillespie. So the man pays his $50.

A third guys walks up with bagpipes. He sits them down and the octopus fumbles with it for a minute and sits it down with a confused look.

"Ha!" the man says. "Can't you play it?"

The octopus looks up at the man and says, "Play it? I'm going to f*ck it as soon as I figure out how to get its pajamas off."
