Guy goes into a bar and sees a tiny little piano player performing in front of the tip jar. Walks up to the bartender in amazement. "That's incredible! Is it real?"
Bartender goes, "Yeah. He plays just any song you want if you put a quarter in the tip jar. All I gotta do is feed him every so often and make sure he gets to sleep go to the bathroom twice a day."
Guy puts a quarter into the tip jar. "Okay, little piano player, can you play 'Fuhr Elise'"? Surely enough, the little piano player starts doing a note-perfect rendition of 'Fuhr Elise.' "That's amazing. Where do you get something like that?"
Bartender says, "Well, I found a magical lamp, but I think it's busted because I only got one wish out of it. I don't really have any use for it, but maybe you'll get something good out of it." He hands him the lamp.
Guy rubs the lamp and the Genie comes out, really cantakerous. "C'mon, man. You woke me from my slumber and I was having the most awesome dream about getting laid with the Olsen twins. What the hell do you want?"
Guy stammers, "Well, I guess you're supposed to grant me a wish, right?"
Genie gets really impatient. "C'mon, man. I don't have all day. What's your wish."
Guy goes, "Well, I guess I'd like to have a million bucks, but..."
Genie says, "Your wish is my command." He claps his hands and disappears back into the lamp. Suddenly, a buck appears right next to him. And then another one appears right after that. Another one appears behind him, which then proceeds to smash glasses and furniture.
The guy starts shaking the lamp and starts rubbing it furiously, to no avail, just as more bucks are appearing in the bar. "Hey, I think this thing's broken!"
"Yeah, I'll say," the bartender goes. "Do you really think I'd ask for a 12-inch pianist?"
