If there's one thing Tom Arnold knows how to do, it's separating people from their money — over the phone.
He figures he made $3 million as a telemarketer, selling supposedly rare coins through boiler room operations on Long Island.

A pleasant, unassuming 38-year-old, Arnold certainly doesn't come off like a con artist. And that was at the top of his bag of tricks.
"The nicer you spoke to people, the better results you would get," he said.
