Based on the novel The Case of the Vagabond Virgin. If I Love Lucy couldn't use the word pregnant, I supposed Perry Mason couldn't use the word virgin. The novel was once again adapted for the series in the final season episode "The Case of the Golden Girls." Of course, for reruns the episode was edited down to an hour. Caren Kaye's part is almost completely edited out. This episode served as the pilot for Jerry Orbach's series The Law and Harry McGraw. Bob Newhart did a Christmas episode for every season of every series except Newhart, where they only did one for the first season. There were six for The Bob Newhart Show, two for Bob and one for George & Leo. He even did a Christmas episode for his 1961 variety show.
