Sister Wives star Kody Brown tried to lighten his load while filming season 4 of Special Forces: World's Toughest Test. "The experience was interesting [and] there's not a dull moment, even when you're sleeping, you're just worried you're gonna get woken up in the middle of the night and dragged out into a pool of cold water in the dry desert," Kody, 56, exclusively told Us Weekly. "My teeth chattered." Kody also recalled that Directing Staff (DS) instructors would "sort of" haze the recruits. "I don't even know what they call the punishment," he told Us.
