I must have missed that episode. I haven't heard it uttered at all. I still enjoy the program nonetheless.
As to Buffy, eh. Never really followed it. But it seems to me that the ultimate evil would be doing some denegrating things to all-things Judeo-CHristian. And marketing-wise, Easter week would get the most viewership (or maybe Christmas).
Just remember, you can always change the channel. Or, I recommend just turning the TV off.
Or put it out for the garbage.
