So, a man walks into a bar.
There's a tiny little piano player in the corner, seated at a tiny little piano. He can't be even a foot tall, but he's really rocking - amazing music - jazz, boogie-woogie, ragtime, one great tune after another.
Astounded, the man listens for a few minutes, then says to the barman, "That's incredible! Where on earth did you find him?"
The barman says, "You're never going to believe this, but there's a genie that lives in the storeroom out back. He'll grant one wish."
Intrigued, the man goes through to the storeroom, and sure enough, there's a genie!
"I am the genie!" announces the genie. "What is your wish?"
The man thinks for a moment, then replies, "I'd like world peace!"
There's a flash of light, a puff of smoke, and suddenly the room is filled with geese.
Disappointed, the man returns to the bar, and says to the barman, "You know, I think your genie's a little hard of hearing."
"Tell me about it!" says the barman with a long face. "Do you really think I asked for a ten inch pianist?"
