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, Im a chiropractor and I could see that you were tense, so I had to massage your back. Sometimes I just cant help practicing my art!

Thats the stupidest thing Ive ever heard! the guy replied. Im a lawyer. Do ya see me fucking the guy in front of me?
