A man walks into a bar and orders a drink. The bartender sets down the drink and the man notices a tiny man playing a tiny piano on the bar.
Intrigued, the man asks the bartender about the tiny piano player. The bartender explains that he found a genie in a bottle in the alley out back and the genie granted him three wishes. The bartender's first wish was for an unlimited supply of the best beer in the world, which now flows endlessly from the taps. His second wish was for a beautiful wife, who is now the most gorgeous woman in the world and runs the kitchen.
The man is amazed and asks the bartender what his third wish was. The bartender grins and says, "I wished for a twelve-inch pianist."
The man bursts out laughing and the tiny piano player looks up indignantly and says, "What's so funny? I'm just trying to make a living here!"
