Guy goes into a bar with a small sack over his shoulder, & asks the  bartender if he would be willing to trade a few drinks for a little  entertainment.  The bartender says, "It depends on the entertainment", so  the guy opens the sack & pulls out a foot high piano player and a  miniature piano.  The little fellow plays a few bars, & the bartender says  "Sure, you can drink all night, as long as this little fella keeps playing".

   The piano player is good, knows all the requests, gets the crowd  involved, the whole 9 yards, & the bartender starts to wonder where he  came from.  He asks the guy who brought him, who says "Well, I actually  got him out in the alley behind your bar.  There was an interesting old  oil lamp out there, and when I picked it up & started to clean it, a genie  came out & told me he'd grant me one wish."  The bartender gets all  excited, & asks the guy where the lamp is.  "It's still out in the alley,"  comes the reply, "it was only good for one wish anyway, believe me, I  tried."

   The bartender figures maybe he can get a wish out of it too, so he  rushes back out in the alley & rummages around until he finds the lamp. Sure enough, when he rubs it, the genie comes out & offers him one, and  only one, wish.  The bartender figures if he has only one wish, it's not  gonna be for a piano player, so he says, "I want ten million bucks."  The  alley is instantly filled with ten million -ducks-, all quacking and  squirming to get out.  The bartender is flabbergasted, and tries to get the genie to correct the error, but to no avail: the genie is gone.  It's all  the barkeep can do to fight his way through the ducks back into the bar.   He cleans himself of feathers and other duck leavings, and confronts the  guy who first discovered the lamp.  He tells him, "I asked for ten million  -bucks-, and I got ten million -ducks-, what gives?  Is the genie hard of  hearing or something?"  The guy replies, "Yeah, that must be it.  You think  I asked for a 12-inch pianist?"
