A mafia family was in need of a collection officer;

...After screening many applicants, they hired an individual who happened to be deaf.
He was very good at what he did, and within a week he had collected $40,000 from nonpayers. However, he was greedy and hide the money for himself.

It didn't take long for the mafia bosses to catch on, so they sent a couple of thugs and an interpreter to find the collector. They found him, took him to an abandoned warehouse, and the two thugs told the interpreter to ask the collector, "Where's da money?"

The interpreter signed to the collector and the collector signed back, "I don't know what you're talking about."

The interpreter told them what he had said. One of the thugs pulled out a .38 revolver, stuck it in the collector's ear, and told the interpreter to as him again.

"Where's da money?" the interpreter signed again.

The collector signed back, "It's in a tree stump in Central Park fifty yards east of the main fountain."
The interpreter told the thugs, "He said that he still doesn't know what you're talking about and that you don't have the guts to pull the trigger!"
