These silly GoPro videos keep popping up and going viral. A lot of people are claiming they are fake. There was one recently of a GoPro falling out a of plane and landing in a pig pen.
This one shows a guy setting his camera up to record his interaction with some monkeys and then a pair of hands grabbing the camera and playing with the it for a bit, even at one point filming himself. Toward the end of the video it appears the monkey is taking the camera out of it's protective casing and you hear some cursing about the camera being in danger.
