There are two versions of this story.
In one, about eight months ago somebody flying in a plane dropped a GoPro camera. The camera fell from the sky and landed, improbably, in a pig pen, only to be found recently by the land owner who took out the memory card and found the complete footage of the descent, which is amazing and has a brilliant ending.
In the other version, somebody just spent way too long faking something that isn't really creative enough to justify the time investment.
Either way, it's worth watching all the way to the end.
