A bass player walks into a bar and sees his two friends, also bass players, sitting beside a 12-inch pianist. He says to his friends, "That's amazing. How did you get that?"
One of the guys hands him a bottle and tells him to rub it and make a wish. He rubs the bottle, and a puff of smoke pops out and a mysterious voice tells him that he can have one wish. So the man thinks and says, "I wish I had a million bucks."
The genie says, "OK, go outside, and your wish will be granted."
The man goes outside, but all he finds are ducks filling the sky and roads. He goes back in and tells his friends what happened, and his friend replies, "I know. Did you really think I wanted a 12-inch pianist?"
