On one hand with have Sam and Cindy. It's purely superficial, Sam only likes her because she is hot. Everyone does. But the thing is, she is boring and shallow. She and Sam don't have the same interests, which is okay. but the necklace thing went too far, she is a stuck-up self-centered bitch. Neil really annoyed me in this episode, he as always only sees the superficial aspect. He'd make a great jock.
then we have Ken and Amy. They are a great couple, have the same humor and interests. They are perfect together. The problem here is that Amy was born as part girl/part guy. And that freaked out Ken, it would freak out most naive heterosexual men. It freaked him out so much because he kinda loved her, it almost made him think he was gay. Of course, back then, being gay meant being into disco.
One of the best scenes of this episode was the conversation between Ken and Sam in the bathroom. It made them both realize what had to be done, Ken going for it and Sam breaking up with Cindy.
There was more going on, but that is what made the episode so great.
