NBC's Fear Factor will return for a sixth season on Dec. 6, replacing The Biggest Loser with, um, Joe Rogan. This go-round, the grossfest will feature a "Home Invasion" segment, in which Rogan springs surprises on unsuspecting homeowners; a heist-themed episode where players try to unlock a sunken armored car; family and reality-star-studded contests; and an episode staged entirely at Psycho's Bates Motel on the Universal Studios Hollywood backlot.
