When I was watching the video, I kept thinking the whole thing is staged too. He has a moving van (is it a rental?). He has the mindset to have it strapped to the wall. Has the mind set to put the straps away before moving the box. Has the mind set to point out it's fragile amongst the other things he points out on the box. Yet he lacks the mindset to use a dolly, have any ramps or tell cameraman to put the stupid camera down and help with the box. After the box falls, he goes into a childish screaming fit.
Having the top of the box open doesn't really mean anything. It could very easily mean he did a cursory inspection of the contents before accepting it.
The only thing that casts any doubt in my mind about it being staged is 3:00 into the film. The other guy appears to ask him a question and ponytail makes motions with his hands. Apparently explaining how the box got in the van in the first place. If this was staged, there would be no reason to ask how it got into the van, he would already know.
edit: Changed the chosen name to prevent giving one of our members, who is much smarter than ponytail, a bad rep.
