Ahhh thanks for the "Sex and the Single Girl" tip, Grant! That's been stumping me for a while now. I was sitting at my computer Googling "Sex and the" over and over, and I think my computer knows me too well because the only results coming up were for Columbo.
Fred, good breakdown on "Butterfly." Now that I think of it, even Fielding Chase's wardrobe seemed to be mostly bland gray suits, etc. That title has always been a favorite of mine because it seemed so obscure, and barely even touches on the murder aspect of the episode.
