Whenever we talk about this episode, we refer to it not by name but by its most famous line, "I've always wanted to make love to an alien!"
I disagree. I think of this episode often, and when I do, I always remember: "This morning, I was the leader of the universe- as I know it. This afternoon... I'm only a voice in a chorus... but I think it was a good day."
This is a wonderful episode, all the more so for not always having to take itself utterly seriously.
