"Tiny pianist" joke

This man walks into a bar with an old shopping bag in hand. He sets the bag on top of the bar and pulls up his stool. The bartender comes over and asks what he'll have to swill.
As he states his preference, something in the bag is moving around shaking the paper bag. The bartender gives a puzzled look but proceeds to the tap. As he's filling the mug, he looks at the bag again and sees that something is still moving around in the bag. He brings the beer over and places it in front of the man. His curiosity gets the best of him and he asks the man what he's got in the bag.
The man reaches into the bag and pulls out a little piano and sets it on the bar... the bartender looks intently at the piano as the man again reaches into the bag... pulling out a small piano bench. He places the bench in front of the piano and again reaches into the bag pulling out a foot tall man. The man sits at the piano and begins playing.
The bartender says,"wow, he sure can play the piano, where'd you get him?"
The guy looks at him and again reaches into the bag and pulls out a genie lamp. He hands it to the bartender and says, "Here, go ahead, rub it.."
So the bartender says, "Is there a real genie in there?"
And the guy says, "Yes, just rub it and see."
So the bartender says okay and begins to rub the lamp... and out pops this beautiful genie. She says, "I will grant you one wish, and one wish only."
So the bartender ponders this for a moment and says, "Okay, I'd like a million bucks."
The genie disappears... and they're both waiting and waiting and nothing happens. They both look at each other and shrug their shoulders.
Then a minute later a duck pops up at the end of the bar. They both look at each other, very puzzled, and then another duck appears... and another, and another... and it continues.
The bartender looks at the guy and says, "I think your genie is deaf. I said I wanted a million bucks not a million ducks."
And the man says, "Yes, I know, do you think I wanted a twelve inch pianist?"
