An old sailor walks in with an octopus. He reaches into his pocket pulls out a harmonica and give sit to the octopus who proceeds to play it brilliantly. After a few tunes the octopus stops playing and looks around - "Oh" says the sailor, "he wants another instrument". "What can he play ?", asks MMario. "I'll give ten dollars to anyone who can find an instrument that he can't play", says the sailor. They try him with piano, concertina, guitar, trumpet, and many other instruments - he's a virtuoso on them all. Suddenly a scotsman produces a set of bagpipes. The octpus leaps on top of them, but only succeeds in getting a seies of terrible sounds out of them. "Hey Jimmy, you owe me ten dollars", says the scotsman. "Hold on" says the sailor, "Give him a bit longer - once he find that he can't hump them, he'll start trying to play them".
