Couples Fear Factor (2) (S04E16)
In this second installment of a seven-part series, nine couples continue their fierce competition for cash prizes, culminating in a grand prize of one million dollars. In the first challenge, partners are chained to a platform and plunged underwater. They must locate a set of keys, determine which one unlocks their chains, and swim to a buoy to stop the clock. The couple that finishes this task the quickest will win two Jeep Wrangler Xs, with no one being eliminated. The second stunt involves a messy sewer transfer, where one partner uses their mouth to fish out cow hearts from a mix of blended animal parts and roaches. They then pass the hearts down a chute to their teammate, who must catch them in their mouth and place them into a bucket, all while the slop continues to drain away.
