Practicing My Art

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 & snarled, "Just what the hell you are doing?"

"Well," said the guy, "you see, I'm a chiropractor & I could see that you were tense, so I had to massage your back. Sometimes I just can't help practicing my art!"

"That's the stupidest thing I've ever heard!" the guy replied. "I'm a lawyer. Do you see me screwing the guy in front of me?"
