For the first time ever, we celebrate our nation's teachers in front of a live audience full of students in a very special Back-to-School episode of "Wipeout." Twenty-four overachieving players will have a spitball fight aboard the "Cruel Bus" on their way to the "Wipeout Skate Park" in this week's Qualifier. Among the teachers competing are The Art-lete and Math Magical, along with the Bad Seed and the Happy History Teacher. Then it's time for a pop quiz on The Hangover, after the field of 12 is narrowed down to six who will then be able to earn a hall pass to the Spin Psycho. The finale also features a special auto tune of co-host Vanessa Lachey -- created by the musically talented and self proclaimed class clown, John Henson -- entitled "School's in Session" that music teachers across the country would certainly give a passing grade to. In the end, only the final three competitors will face off in what will be a true schoolyard rumble at the Wipeout Zone for a chance to bring home the $50,000 cash prize!
