Chiropractor In Line

In a long line of people, one guy suddenly starts massaging the back of the person in front of him, the person turned and asked, what the hell you are doing?

"Well," said the guy massaging the back, "you see I'm a chiropractor and I can't help massaging your back, in fact I can't help practicing my art".

"Are you crazy?" the other guy said, "I'm a lawyer, am I fucking the guy in front of me!"
