I thought it was a neat and great episode. I though theo whole homage of animated Xmas specials, plus Charlie Manson was a unique twist. Here's some things I didn't understand...
-Cartman's sleeping bag doesn't have Erkel on it.
That's it. I guess this episode never puzzled me on bit. I do wish they've finished the last song at the end however, I didn't mind Stan's regular "fucked up" remark, but they could've least had the last line of the song (after Stan's line) dubbed over the Braniff logo before the CC tag. That's my improvememt for this episode.
