Hey assholes...
Not that anyone is ever going to read this -
But no SHIT this song was by Weird Al. Considering Dave was paid to make this video(probably), it's probably Al's property now, and coupling that with the fact that there was the "added bonus" of being able to play the demo of an unreleased game, it was probably a promotional stunt, and therefore it's most likely with Mr. Yankovic's expressed permission.
Anyway, that crap aside, thanks much for posting this here. Love the video, it's very funny, and cool. The only things that threw me off were the School Play scene (But that's your style, eh? It can be hard to make filler scenes for sure...), and George Bush...It really didn't seem to fit, but eh, I don't know humor. But yes...Very nice movie overall!
