"That was an insult" joke

A man came storming out of the courthouse ranting and raving; obviously really angry . He stomped accross the street and into the bar and flounced down on a stool muttering, "Asshole attorneys". The man next to him recoiled in outrage saying "I want you to know I highly resent that remark"."Why, are you an attorney?""No, I'm an asshole."
