Fine, 005 and Fink convinced me, I think I will watch South Park: Bigger, Longer & Uncut tonight for the first time since it was in theaters (1999, it has been over ten years since I have seen it; that is crazy to think about).
Re: Cartman's voice. I read that originally Trey did the Cartman voice on his own, but now he does a different voice and they change the pitch electronically to make it sound like the original Cartman voice. This was probably because it takes a lot of effort to do that sort of voice and probably gets painful after a while.
I really don't have a problem with that, I think the "new" Cartman voice resembles the old one enough and is still funny, or at least as funny as a voice can still be after fifteen years of hearing it. Although that scene with him yelling at the cat did have me in tears just now.
