The manliest celebrity around, Bear Grylls, is creating quite the media empire capitalizing on his proclivity for self-punishment. For his series Bear Grylls: Mission Survive, the super hottie subjects a group of eight celebrities to twelve days in a remote location, where they must use brains and brawn to live off of the land. Jokester and exhibitionist Grylls looks Bear-y nice as he flashes his sculpted ass in front of a crowd!
