So a guy walks into a bar one day and he can't believe his eyes. There, in the corner, there's this one-foot-tall man, in a little tuxedo, playing a tiny grand piano.
So the guy asks the bartender, “Where'd he come from?”
And the bartender's, like, “There's a genie in the men's room who grants wishes.”
So the guy runs into the men's room and, sure enough, there's this genie. And the genie's, like, “Your wish is my command.” So the guy's, like, “O.K., I wish for world peace.” And there's this big cloud of smoke—and then the room fills up with geese.
So the guy walks out of the men's room and he's, like, “Hey, bartender, I think your genie might be hard of hearing.”
And the bartender's, like, “No kidding. You think I wished for a twelve-inch pianist?”
