Joke about a genie.....???

here's the joke:

A guy walks into a bar and notices that there is a twelve inch person playing the piano and he thinks that's a little strange.

So, the guy walks up to the counter and notices a weird looking bottle. He asks the owner, "What's in that bottle?"

The owner answers, "It's a magic lamp."

The man takes the magic lamp, rubs it, and a genie appears.

"You get one wish," says the genie.

The man thinks and says, "I wish for one million bucks."

The genie nods his head and disappears. A second later one million DUCKS appear in the bar.

"What the heck?! I wanted one million BUCKS!!!" yells the man.

"well, says the bar owner. I tried the magic lamp too. And you know what? I didn't want a twevle inch pianist."
