Yes, now when you reminded me I remember. Very squicky.

In South Park, there was music in the anime fashion, and the gratuitous violence of the ep fit within the context of the story. It worked on every level for me, and I don't even watch anime or read mangas or whatever.

Maybe BtVS doesn't work the way South Park works because, unlike South Park, BtVS was supposed to be about Serious Things? Then again, maybe this issue was intended as a big joke. :)
