We hope tonight's Jeopardy! contestants didn't spend too much time brushing up on "World Literature" or "Popular Novels."
Instead, book club tastemaker Oprah Winfrey provided all the video clues for her own Double Jeopardy! category, "Oprah's Favorite Books," quizzing contestants on Steinbeck, To Kill a Mockingbird and other high-brow fare.
The category looked to be a sure moneymaker, so who knows why, after banking $800, defending champ Adam Bibler switched to "Middle Names," where he didn't know his James Buchanans from his Rutherford B. Hayeses.
