I just saw the millenium episode, and I once again find myself mystified by Butters' unexplained appearance. I thought he was supposed to be a "melvin" and the other kids in the group hated him, yet here he is again standing alongside the usual surviving threesome at the New Years Eve gala at Vegas.
I recall reading here that he's supposed to be just some annoying kid who talks too much and makes a stupid comment about everything, but here, he is given a non-speaking role. What was he doing there, and what are the writers' intentions with him? Is he supposed to represent Trey Parker in some way (similar hair) or the way he was as a child? That would make a bit of sense considering that the other melvin in the "Two Men Jacking Off..." episode was a curly-haired, spectacled math nerd like Matt Stone, and he was in the first grade, making him two years younger than Butters like Matt is to Trey. Are they trying to work him into becoming one of the regulars, perhaps eventually replacing Kenny?
Just curious.
