A man walks into a bar with an octopus.
"My octopus can play any instrument," he exclaims. "I'll challenge anyone at the bar to find an instrument he can't play. If he can play it, you owe me a drink. If he can't play it, I'll buy drinks for the entire town."
Since the piano is sitting right there, a few people challenge the octopus to playing it. The octopus sits down and starts playing Beethoven's Moonlight Sonata flawlessly.
Next they find a guitar, and the Octopus plays Tarrega's Recuerdos de la Alhambra.
They bring him a violin, and he plays Paganini's Caprice 24.
One instrument after another, the octopus can play it. The harmonica, the flute, the banjo, the bassoon - he can play them all. The whole town is abuzz with news of this octopus and his musical talents.
Finally a Scotsman walks into the bar one day. He's heard of this octopus from afar, and he brought his bagpipes with him for the challenge. He figures, even is the octopus plays them, it's worth buying the owner a drink just to see it.
He gives the octopus the bagpipes. At first, the octopus handles them very gently. He slowly wraps his tentacles around the pipes and puts his mouth up to them, but as he's about to play, he starts getting finicky. The expression on his face turns frustrated, and he starts twisting around and struggling with the bagpipes.
The octopus owner is getting worried. He sees the octopus getting all tied up in knots. He tries to encourage the creature. "C'mon, buddy. You can play it, right? Play those bagpipes. Just calm down, concentrate, collect your thoughts, and play."
To this, the octopus replies,
"Play it? I'm trying to get these stupid pajamas off so I can fuck it."
