Two guys bet fifty dollars each that the octopus can't play their instruments.

The first guy hands over his French horn and the octopus starts to play it.

The second guy hands over his tuba and sure enough the octopus starts to play it.

The bartender then walks into the back room and comes back five minutes later with a set of bagpipes and bets all the money in the drawer that the octopus wouldn't be able to play it. He hands over the bagpipes to the octopus and waits.

After about a minute of watching the octopus run its tentacles over the bagpipe the owner of the octopus says, "Come on now! Play it!"

The octopus replies, "What do you mean play it?! If I can figure out how to get the plaid pajamas off of it, I'm gonna screw it!"
