While filming for the Great Bear Stakeout for Discovery and the BBC, photographer and grizzly expert Brad Josephs strapped a GoPro to a rock with a rubber band, hoping to get some footage of the enormous beasts. The video he got was a lot closer than anyone expected, when the bear decided to chew on the camera.You can see the footage below of two bears who come to inspect the impromptu camera rig — with their mouths. According to Josephs, this is an older mother, and a younger, three year old cub.
