The previous reviewer may not realize that this episode was intended as a back door pilot for a new series centered on Lester and Dr. Fong. Many series do this including The Rockford Files with Just Another Polish Wedding as a spin-off called Gabby & Gandy and the Richie Brockelman episodes. Magnum PI did this with Birds of a Feather and the earlier episode, J. Digger Doyle. The title character typically features less prominently as in this episode. Many are good episodes in their own right, though some are less so. It was a common practice of the time to introduce a new show using a popular show. Lester is a recurring character, featured in four episodes, and the introduction of Keye Luke provides an interesting contrast. I would have been willing to watch more such episodes to see how their chemistry developed.
