Not really a conversation:
I had a complete ass as a law school professor. There could have been a drinking game based on his lectures: Take one drink every time he says something about how great he is. Make it a double if it relates to his having a black belt. The class would have been bombed in an hour with this jerk. And I had a friend/classmate who could have wiped the floor with him, as she was quite a bit past, as she said, "only a black belt?"
So arrogant, he naturally doesn't realize it. While in court on a case, a friend of mine heard the attorneys discussing whom to get as a mediator. One named this jerk to the judge. The other attorneys in the courtroom were split between laughing and moaning. Yeah, a real legend in his own mind.
