Ha! I love this video!
I think it's a joke, though. I mean, the guy does sort of curl it at some point.
I don't remember the specifics, but when I first found the video a few months ago I think I read (maybe in the youtube comments) that this guy was making fun of a dude on a different forum who always posted DL vids. Apparently the guy always posted vids of himself lifting pretty heavy but with horrible form and then bragged heavily about it. Something like that.
Even though I know it's a joke, it still cracks me up every time.
