Well, on his first week, the deaf collector picks up over $40,000. He gets greedy, decides to keep the money and stashes it in a safe place. The mafia soon realizes that their collection is late, and sends some of their hoods after the deaf collector.
The hoods find the deaf collector and ask him where the money is. The deaf collector can't communicate with them, so the mafia drags the guy to an interpreter.
The mafia hood says to the interpreter, "Ask him where da money is." The interpreter signs,"Where's the money?"
The deaf replies, "I don't know what you're talking about."
The interpreter tells the hood,"He says he doesn't know what you're talking about"
The hood pulls out a .38 and places it in the ear of the deaf collector. "NOW ask him where the money is."
The interpreter signs, "Where is the money?"
The deaf replies, "The $40,000 is in a tree stump in Central Park."
The interpreter's eyes light up and says to the hood, "He says he still doesn't know what you're talking about, and doesn't think you have the balls to pull the trigger."
