On Ken Jennings

America's Hardest-Working Know-It-All: Ken Jennings transcended the show by being the epitome of the show. Jennings — Ken Jennings to America, that type of name you can't help but pronounce in full, to the extent that even his then 2-year-old son would call him Ken Jennings during his six-month run — became a celebrity in a celebrity-free zone. If Trebek is the show's Virgil, Jennings is Dante, the one guy who made it out alive. Even if you're the kind of person who knows that the Tournament of Champions, the show's annual best-of-the-best showdown, started yesterday, we bet you that you can't name another Jeopardy contestant. (OK — except for Leonard, the daring and daringly Afroed Teen Tournament champ who became a star Tuesday night.)
