The Four AM Mano-a-Mano Bonus

Many teams offer an additional challenge or puzzle or competition during the 4 AM break. The most common and most popular seems to be the simple Mano-A-Mano format. Each team sends down one player (in the parlance, their "mightiest trivia warrior") without books, friends, or anything but a working pen, to face a trivial challenge unknown.
