This long line of people are queueing up to get served in a shop. Suddenly one bloke starts massaging the person in front's back. The other bloke immediately turns round and says to him, "What the hell do you think you're doing?"

 

The bloke behind tells him, "Well, I'm a chiropractor and I can't help myself. I can't help practicing my art."

 

"Are you crazy?"

says the bloke in front, "I'm a lawyer, but do you see me f**king the bloke in front of me?"
