Two human beings found themselves stripped of everything but their sense for drama on Saturday night's Naked And Afraid, the Discovery Channel series that answers the question, "Will people watch a no-stakes version of Survivor if there are enough bare butts onscreen?" Tom, an army vet and Carrie, a marine, were set down in Cambodia. Parents need to know that the reality series Naked And Afraid features men and a women who do not know each other sharing a 21-day survivalist challenge without food, water, shelter, or clothes. Despite frequent images of bare bottoms (other private body parts are blurred), it is not sexual, and focuses on.
