I have to disagree with you here, however; the content of the episode in question is the sort of thing I'd expect to find in a crackfic - written because it's too insane an idea to just be left alone, enjoyable in its own way but not remotely on the level of something actually intended to be good - and it isn't improved significantly IMO by having been animated.
