I had a really really hard time watching this episode in particular. I don't know who came up with the Evolution (we came from monkeys) junk, but He/She must have been on drugs at the time. It's like adding 2 + 2 and getting 5; it just doesn't work. All you have to do is open your eyes and look around you to know that there is a God and He created us and everything that we see. If someone tried to force those ideas on my child and tell them that they couldn't disagree, I would be having a sit down with the principal.
I remember squirming with extreme discomfort over the sheer *badness* of this episode. I could find nothing at all to like about it.
The regular cast was competent, as always, but the story was just -- arrrrgh!!
I just wanted to reach inside the tv, grab the guest characters around the neck and strangle them, or at least slap a little common sense or reality into them.
