After a month in Jamaica, it is all down to the final challenge for the $150,000 Chili's dollars! Mark, Colin, and Jamie are going head to head with Lori, Ruthie and Ellen to see whose going to win the Battle of the Sexes. With their losing streak ov... (more)er, the ladies are confident that they have a chance to win... Each team is given a block puzzle as a clue for the mission that is to come. The ladies figure out the puzzle but the guys can't and Mark hopes this isn't a bad sign. After they receive the phone call with details, the teams arrive at the competition course. The game is called ""It Takes 3"" and will require each trio to work as a team in order to win. The first part of the course is the tri ski slalom, followed by the block-by-block brainteaser, and then the ropes course. No member can advance to the next phase without every person on his or her team completing the obstacle. The horn blows and the mission begins... The guys quickly get in a groove and finish the ski-slalom first.
