A guy walks into a bar, sits down, opens up a suitcase and takes out a tiny piano, followed by a very small man - only a foot tall. The tiny man sits and starts playing the tiny piano. The guy sits and stares at him, a glum expression on his face.
The bartender, enchanted by the tinkly music from the tiny piano, walks over to the guy and says "Hey buddy, what's up with the little dude? He plays real nice!"
"Well, you see," says the guy sadly, "I found this lamp, and when I rubbed it this genie popped out and said that he'd give me one wish. And this is what I ended up with."
"But this is great! The little guy is a great player! Why are you so sad?"
The guy looked up at the bartender.
"Do you really think I asked for a twelve-inch pianist??"
