A character in this episode is named Doctor Eugene Twombly. Bea Benaderet's (who plays Cousin Pearl Bodine) husband's birth name in real life was Eugene Twombly.
Dr. Twombly's office is created by re-arranging props around in the set they use for Mr. Drysdale's bank office.
Dick Wesson, who plays Dr. Twombly's patient, was also one of the show's writers.
