A man walks into a bar with an ostrich and a midget.

He sits down at the bar with the ostrich and orders a drink while the midget walks over to the piano and begins playing some tunes.
The bartender pours the drink and the man pulls out the exact change from his pocket. This continues for a few rounds until the bartenders curiosity gets the better of him.
BT - How do you have the exact change for each round of drinks?
M - I was granted 3 wishes by a genie, I asked to be able to pull the exact amount of money from my pocket for whatever I wanted to purchase.
BT - Okay, so what about the ostrich?
M - The next thing I asked for was a chick with long legs.
BT - So how does the midget on the piano fit into it?
M - Well, I certainly didn't ask for a 12 inch pianist.
