This is a video of a man cutting down a tree. Since it was posted online, you know that something went wrong, because who would go online to find a video of a guy successfully cutting down a tree? No one. No one at all.
This guy was attempting to cut a pretty big limb off a tree approximately 20 feet up. Well, he was successful in getting the branch to the ground, but the branch was also successful in getting HIM to the ground. So...I guess they're even?
