A lawyer and a chiropractor

A lawyer is standing in a long line at the box office. Suddenly, he feels a pair of hands kneading his shoulders, back, and neck. The lawyer turns around.

"What the hell do you think you're doing?"

"I'm a chiropractor, and I'm just keeping in practice while I'm waiting in line."

"Well, I'm a lawyer, but you don't see me screwing the guy in front of me, do you?"
