Leeches, Shaved Heads and Tear Gas, Oh My! Part 1

Struggling to keep their wits about them, contestants in this episode have to endure being bound and locked in a cage that is slowly submerged underwater while their teammate has to dive in and struggle to free them before they run out of air. At the aptly named “Fear Factor Food Truck,” teammates are forced to eat a box lunch of live cockroaches and giant grasshoppers, accompanied by a side dish of rat hair chips and a special salsa topped with maggots. In the final stunt, one team member must leap back and forth from a swerving bus to a trailing car driven by his/her partner, in a timed race to retrieve flags the fastest. One team will remain standing and claim the $50,000 cash prize.

The four new teams of couples assemble: Joel and Andrea, "party people" who met in Vegas; DJ and Brooklyn, a careful 19-year-old number cruncher and an 18-year-old risk taker; Todd and Carole, a married couple out to prove that 50 is a badge of honor; and Roberto and Tanya, a determined power couple. Their first challenge involves getting catapulted off a building onto a rope net, where they must gather 10 flags a piece as quickly as possible while being rained on the entire time. The team with the worst time is eliminated.
