Doing scary stuff to win prizes.In each pulse-racing "Fear Factor" episode, contestants (sometimes solo, often paired with spouses, siblings or best friends) recruited from across the nation must decide if they have the guts and determination to face their most primal fears. Under the supervision of professional Hollywood stunt coordinators, contestants are confronted with a series of challenging stunts. If they complete their task they advance; if fear stops them from completing a stunt or they fail the mission, they are immediately eliminated. The contestant who wins the final challenge takes home the prize.—Matt Kunitz
