Oz in Jeorardy!

From the November 25 episode, in the Jeopardy! round was a category called Chick Lit, which was all about books with chickens in them. Naturally, for $400, this was the clue:

Mariusz, the challenger at the center lectern, rang in first and correctly responded, "Who is Dorothy?" He earned $400 for knowing that (or figuring it out) and, unlike some recent contestants who knew their Oz clues, went on to handily win the game.
