Guy walks into a bar with a big box and sets it on the counter. He asks the bartender if he's in the market for entertainment for his bar and opens the box. Inside is a tiny man and a tiny baby grand piano. The guy nods at the little man and he begins playing beautiful music on the piano.
"That's amazing! How'd you manage to find this little fella?"
The guy is frowning. He sighs noticeably and says "I freed a genie and he granted me a wish. I guess he was either a prankster or just hard of hearing."
"Why do you say that?" asks the bartender.
"Do you really think I would wish for a 12-inch pianist?"
