Damn it! Youtube's down for me at the moment. Well, right now I'm sure I can say that whatever this video is, shouldn't be taken seriously. If it's a parody, it's meant to be a joke.
I've done my own interpretation video on COB, and some others. I especially got some prats commenting on my Darkthrone one going "How could you mock pure black metal, black metal is the only "tr00" thing in this wretched life" ... Blagh blagh. Get a life! I love Black Metal too! But if you feel so bad about life you should just get off YouTube and hang yourselves.
Stuff like that shouldn't offend people. I'm sure this video was just made for a laugh, especially for COB fans, who actually know of the band.
