Fear Factor Couples (2005)

Four couples competed in three stunts, with the winning team dividing the prize (and, in season 3, sending one player to the Tournament of Champions).
In Season four, nine couples competed over seven weeks and 17 stunts for $1,000,000. Along the way, they competed for various other prizes, including $10,000, cars, vacations, credit cards, and a chance to steal a desired prize from another team. In Season five, eight couples competed for the million dollar prize.
