"Here," says the bartender, handing the man a genie lamp, "rub this."
So the man rubs the lamp and out comes this genie.
"What do you wish for?" asks the genie.
"A million bucks," the man states, quite sure of himself.
"Granted." And the genie claps his hands and disappeared back into the lamp.
The man looks around, checks his wallet but can't find a million bucks anywhere. Just that moment, a million ducks fly through the bar. Astounded the man says: "Hey! I didn't ask for a million ducks!"
"Do you think that I asked for a 12 inch pianist?" replied the bartender.
