A man walks into a bar and orders a beer. As he sits down at the bar, he notices a tiny man playing a tiny piano on the counter. He asks the bartender about the little man and the bartender explains that he found a genie in a bottle and was granted one wish. The man wished for a tiny piano player to entertain the customers.
Intrigued, the man asks the bartender if he can make a wish too. The bartender agrees and the man closes his eyes and wishes for a million bucks. Suddenly, the bar is filled with a stampede of ducks quacking and flapping their wings. The man looks confused and asks the bartender why he got ducks instead of bucks.
The bartender shrugs and says, "Do you really think I wished for a 12-inch pianist?"
