This reminds me of :
A man walks into the ground level of a law firm and gets onto an elevator where there are already two men standing at the front having a conversation. He steps to the rear to wait out the ride. Meanwhile the two in front continue their mostly quiet conversation that is occasionally broken when one of them speaks up about this or that. The conversation seems to reach some sort of peak when the one of these two men exclaims " yeah, but all lawyers are a**ho**s ! ". The man at the rear then speak up " hey, I am offended by that remark! ". In harmony the other two men reply to him "oh, we are sorry. Are you a lawyer ?" The man in the back says " no, I'm an a**ho** ".
