As a faithful X-Files watcher I'd have to say this episode still sticks out in my mind as one of the most bizarre. This was a stand alone episode - with no impact on the overall Conspiracy Theory theme of the show, but a great thriller nonetheless. The Peacock family sons keep impregnating their own mother to create disfigured & grotesque offspring, she who is deformed herself. The horrific storyline though is that this seems completely normal to this family, which makes the episode so intense. It left me spooked & shaken - so apparently the writers & actors did an excellent job! Every time I hear the song "Wonderful Wonderful" I go right back to that episode.
