Fred Gwynne plays what might be his first comedic role since portraying Herman Munster...and he acted in more Mystery Theater episodes on the radio (82 to be exact) than any of his TV series.

His role is Peter Perkins in Peter Peter Pumpkin Eater, a comedy about a man who lives a Walter Mitty-style life to escape his problems. Peter becomes increasingly unable to distinguish between reality and his fantasies, which gets him into trouble with a gangster in real life.
