A young man is sitting in a bar, drowning his sorrows, when another fellow sits down near him and orders a drink. The newcomer opens up his backpack and takes out a toy grand piano and sets it on the bar, then reaches up on his collar, and to the astonishment of the onlookers, helps a tuxedo-wearing man only a foot tall down to the piano where the diminuitive fellow cracks his knuckles and begins to play, beautifully.
The young man looks at the newcomer and says "That's amazing! Where did you find him?"
The newcomer takes a drink and says "Got him from a wish. I'm from Ireland, and there's a leprechaun that's followed my family around for years. Can't get rid of him."
The young man perks up and thinks this could reverse his fortunes. "I don't suppose I could ask him for a wish?"
"Suit yourself," the newcomer says, and snaps his fingers. A tiny man, dressed in green and looking incredibly ancient, appeared on the bar. "This young lad wants to know if he can have a wish, friend," said the newcomer.
"Why doesn't he just ask the barkeep if they serve fish, then?" said the leprechaun.
"No, a wish!"
"Oh, alright then. What's your heart's desire, lad?"
The young man thinks for a moment and says "Well, it may be cliche, but I wish for you pot of gold!"
*POOF* The pianist began a mournful tune, as the young man regarded a large pot filled to the brim with black mold.
The young man turned to the newcomer, who was still taking swigs of his drink. "A might bit hard of hearing, is he?"
"Did you really think I wished for a 12-inch pianist?"
