In the pilot episode, Michael goes through the back room of Babylon looking for Brian. On his way, He sees another friend (who's having sex) and says, "Hey, Todd! How's it going?" Todd looks at him and says, "Fine!" A different character asks Todd the same thing in the first episode of every season.
I just rewatched the first part of season five and, indeed, there's todd getting asked that very question, and answering fine.
