In a long line of people waiting for a bank teller, one guy suddenly started massaging the back of the person in front of him. Surprised, the man in front turned and snarled, "Just what the hell you are doing?" "Well," said the guy, "you see, I'm a chiropractor and I could tell that you were tense, so I thought I'd massage your back" "That's the stupidest thing I've ever heard!" the guy replied. "I work for the IRS. Do you see me screwing the guy in front of me?"
