Overview: Richard Hammond and Amanda Byram present the second of two celebrity editions of the world's silliest extreme obstacle course-based game show. This special sets celebrities the task of conquering the Sucker Punch, the Big Red Balls and Crash Mountain. For the winner, invitations to appear on a lot of daytime talkshows and a cheque for 10,000 pounds to the charity of their choice. For the losers, a face full of Argentine mud. It's a win-win situation.
