From Primetime to Daytime: And Then, I Wrote (Bewitched, 1965)

 From season 2 of Bewitched:

With Samantha pregnant with Tabitha, she needs to find something to pass the time, and, with the encouragement of a prospective client of Darrin's (Olan Soule, The Andy Griffith Show), who is also a psychiatrist, Sam decides to do a Civil War story. Endora's meddling brings some of the characters to life, and that sends snoopy Gladys Kravitz to the shrink's office!

In front of the camera, Olan Soule made a career out of playing doctors, judges, and coroners. His role as choir director John Masters on The Andy Griffith Show fit right into his rep as an Everyman actor.
