It's the Pirate Special! This means tweaks to the course for the group of contestants that includes, to mention a few, a 'real' Viking, an army officer, and an Above-the-Average-Joe. And one of the 20 *will* pass the Big Balls.
All the obstacles have been introduced, but the contestants include, among others, a self-proclaimed ninja and an analyst who claims he knows how to clear the Big Balls.
