Another "man walks into a bar" joke...
 

Man walks into a bar, sees this 12" tall man playing a paino...he goes to the bartender and asks about him - he says there's this magic lamp, I rubbed it and a genie popped out, I made a wish, and there he appeared.

He asks to try it, bartender says sure...you only get one wish...

Man rubs the lamp a genie comes out, and he tells the genie his wish. Next thing you know a whole shitload of ducks come flying through the bar, making a mess of the place...

The man looks at the bartender confused, and the bartender says, you idiot...you shoulda known he was deaf - do you really think I asked for a 12" Pianist?
