So I was watching an episode of the old Hardy Boys/Nancy Drew Mysteries on DVD. It was one of the Nancy Drew episodes with the delectable and underrated Ms. Pamela Sue Martin (a real beauty) about a vagrant who claimed to be Santa Claus. There were these two little children in the story--a brother and sister pair. The little boy seemed awfully familiar to me, but I just couldn't figure out who he was.
It wasn't until the credits started rolling that I realized it was Sparky Marcus, the young lad who played Arthur Carlson's son on an episode of the classic WKRP in Cincinnati. I should have realized that a lot sooner, especially since I had just watched that episode not long ago. Nice work.
The little girl, by the way, was Missy Gold, who later played sweet and adorable little Katie on Benson. I sure didn't recognize her, possibly because of how she matured during those intervening years. I sometimes wondered what happened to her, and whether she went on to play anything else after Benson. Her IMDB entry says that she did, but not much, which is a bit of a shame.
