Wanna Bet? is a weekly, one-hour primetime event in which celebrities wager on challenge-performing contestants. The celebrities judge the performers and have the chance to earn big money for the charity of their choice by betting on the success or failure of the wildest tricks and mental challenges that ordinary Americans -- housewives, truck drivers, dentists -- can dream up and perform in front of a studio audience. Hosted by British comedy sensations Ant and Dec, Wanna Bet features celebrity contestant/judges including Sherri Shepherd, Tom Bergeron, Scott Hamilton, Bill Engvall, Jerry Rice, Drew Lachey and Corbin Bernson. Challenges include: Skiing over 2000 fresh eggs without breaking them, solving a Rubik's Cube blindfolded and submerged under water in under 20 seconds, memorizing 32 audience members' first and last names in under 60 seconds, and a 20-piece marching band piling into a small van while playing "When the Saints Go Marching In."
