The godfather
A Mafia Godfather finds out that his bookkeeper has cheated him out of $10 million bucks. His bookkeeper is deaf. That was the reason he got the job in the first place. It was assumed that a deaf bookkeeper would not hear anything that he might have to testify about in court.
When the Godfather goes to confront the bookkeeper about his missing $10 million, he brings along his attorney, who knows sign language. The Godfather tells the lawyer 'Ask him where the $10 million bucks he embezzled from me is'. The attorney, using sign language, asks the bookkeeper where the money is?
The bookkeeper signs back: 'I don't know what you are talking about'. The attorney tells the Godfather: 'He says he doesn't know what you're talking about'. The Godfather pulls out a pistol, puts it to the bookkeeper's temple and says, 'Ask him again'! The attorney signs to the bookkeeper: 'He'll kill you if you don't tell him'! The bookkeeper signs back: 'OK! OK! You win! The money is in a brown briefcase, buried behind the shed in my cousin Enzo's backyard in Queens'!
The Godfather asks the attorney: 'Well, what'd he say'? The attorney replies: 'He says you don't have the balls to pull the trigger'.
