Is that his picture? lol. . . .
I take it you have no idea who the guy is either.
That's Nathan Thurm.
"This was a character created by Martin Short. A shady lawyer, Thurm was a chain-smoker, quite paranoid, and constantly in denial about his paranoia. "I'm not being defensive. You're the one who's being defensive." When questioned, his catch phrase often included, "It's so funny to me that you would think..." He would also look into the camera and express his puzzlement at the questioner by asking, "Is it me, or is it him? It's him, right?" Other times, he would deny an accusation, then immediately reverse his position when the accuser reaffirmed the statement. "No, it isn't!" ("Yes it is.") "I know that! Why wouldn't I know that? I'm well aware of that!"
Perhaps the best known appearance of Thurm was in a 1984 SNL sketch that was a send-up of 60 Minutes. Harry Shearer played Mike Wallace, accusing Thurm of being involved in corporate corruption. Thurm of course denied everything and nervously tried to turn the tables on Wallace."
