Jeopardy! champ Ken Jennings recently answered questions in an online forum about his experience on the popular quiz show. When asked what category would be a nightmare for him, the trivia buff answered, “Country music...That or hockey. Least favorite categories.” He added, “Basically anything with a mullet is my Jeopardy kryptonite.” Jennings won 74 Jeopardy! games in a row, picking up nearly three-million dollars in total prize money on the show.
