A Mafia gang takes on a deaf man to run their deliveries, feeling it would be safer having someone unable to overhear conversations.  However, one day when he is to deliver a large sum of money, he never shows up with it.  The mobsters track him down, but don't find the money on him.  As none of them are able to use sign language, they bring in an interpreter.

Mobster: "Where'd you hide the money?" (Interpreter signs the question.)

The bag man signs his reply.  The interpreter says, "He says he had to ditch it in the river because the cops were onto him."

Mobster:  "I'm not fooling around!  You better tell me where that money is!"  (Interpreter again signs.)

The bag man signs his reply, and the interpreter relays, "He swears he is telling the truth.  He had to get rid of it."

The mobster pulls out a revolver and points it between the deaf man's eyes.  "Tell me where that money is, or I'll kill you right now!"
(Interpreter signs his statement.)

The bag man, sweating profusely, signs, "It's inside a shoebox under a loose floorboard in my bedroom closet."

The interpreter says, "He says he doesn't know where it is and he doesn't think you have the guts to pull the trigger."
