Octopus

So this guy walks into a bar with his pet octopus and says to the people in the bar "I bet you $50 that none of you have a musical instrument that my pet octopus can't play". So this guy who happens to have a guitar with him gives his guitar to the guy who hands it to the octopus. The octopus takes hold of it, tunes the strings and plays a flawless piece on the guitar. The owner of the guitar gives the octopus guy $50.

Next someone hands the octopus a trumpet.

The octopus takes it and plays an incredible jazz solo on it. Again, the owner of the octopus pockets $50.

Finally, the bartender leaves the room for a few seconds and comes back with a set of bagpipes. HE says to the guy "if your octopus can play this I'll give you $200". So he hands the octopus the bagpipes and the octopus looks at it, turns it around, looks at it from another angle, turns it upside down and his owner whispers to him "hey, stop pissing about and play the damn thing" and the octopus says "play it? if I can work out how to get its pajamas off I'm going to fuck it".
