A man walks into a bar with a tiny piano and a 12-inch pianist. He sets the piano on the bar and the tiny pianist starts playing beautiful music.
The bartender is amazed and asks the man where he found such a talented pianist. The man explains that he found a magic lamp and was granted one wish. He wished for a tiny pianist who could play the piano.
The bartender is skeptical and asks to see the lamp. The man pulls out the lamp and rubs it, and a genie appears. The bartender is excited and asks for a wish of his own.
The genie grants his wish, and suddenly the bar is filled with ducks. The bartender is confused and asks the man what happened.
The man shrugs and says, "Well, I did wish for a 12-inch pianist."
