Overview:The ultimate social experiment begins when seven beauties and seven geeks move into an enormous mansion in Los Angeles. After choosing teams, Brian explains the first challenge, where the women and the men must learn from each other to complete tasks. All of the contestants must rediscover the fifth grade; the women compete in a trivia contest, focusing on history, spelling, and geography. Meanwhile, the men learn dance moves from the women, who then must perform in front of a crowd of people, who judge who danced the best. Mindi and Richard win both of their challenges, ensuring them full immunity and giving them the power to nominate two other teams for elimination. At the elimination ceremony, Richard and Mindi send Eric and Cheryl and Joe and Erika to the elimination chamber, where Eric and Cheryl are eliminated.
