Guy sits down at a bar pulls out a foot tall piano player and piano and orders a drink while the piano player plays. The bartender amused by this askes where he got such a small piano player and piano. The guy explains to him there is a genie down the street granting wishes. The bartender leaves the bar, finds the genie and askes for "a million bucks". Poof the genie is gone and the bartender is left with a million ducks. Discouraged he rounds up his ducks and returns to the bar. He tells his story to the guy with the tiny piano player. The guy replies "what you think I asked for an 11 inch pianist"

The version I heard the guy had a 12" long cigarette lighter and was lighting a cigarette.

"What, you think I wished for a 12" bic?"
