Twelve Inch Pianist
This guy walks into a bar, pulls out a tiny piano and stool, and a tiny little man. The tiny man sits down, and starts to play the piano. This other guy notices it.
“Hey, what's that?”
“A twelve-inch pianist. Ya see, I found this magic lamp, rubbed it, made a wish, I got a twelve inch pianist.”
“Can I try?” The man with the piano agrees and a minute later, a million ducks fill the room.
“Ducks? I didn't wish for a million ducks, I wished for a million bucks!”
“Ya think I really wished for a twelve inch pianist?”
