Something else I liked about the episode is that even though the guys grilling Jayne Mansfield about literature at a party were kind of mean to her, still - they were talking about books! At a party! And that I believe really did go on.
Poor Barry Coe, his career went nowhere after this series ended. (Gary Lockwood was the only real beneficiary of Follow the Sun.) He wound up taking smaller and smaller parts, made a few exploitation films in the early 1970s, and suffered the final indignity of being reduced to playing Mr. Goodwrench in TV commercials. By the early 1980s he appears to have dropped out of the industry altogether. He apparently is still alive somewhere, aged 80.
