!! OMG he's naked: Bear Grylls !!
Outdoor wild man Bear Grylls of the show "Man vs. Wild" likes to take off his clothes when getting into or out of things. Mud. Rivers. Frozen lakes. Lava. Any excuse to get naked, hey Bear?
Though Discovery Channel doesn't show the dingle-dong, they allow the butt - so check out his NSFW smooth bottom after the jump.
