I loved it. Was also going to comment that it was well done as in one large take. Speaking of well done single take shots, wasn't there a movie done a while ago that was one single take for the entire thing? (Someone may have mentioned it above, I don't remember the name, it was old, as in old style, in some large victorian age (maybe) building.)
Anyway, great way to start my morning, I liked the first guy after Wierd Al and Jack Black, the first few girls were... meh not that funny.
