Dr. Morgan (Troy Donahue) tells Patty Lane (Patty Duke) that he is going to Africa to help Albert Schweitzer. While Schweitzer was still alive at the time that the episode was filmed, he died on September 4, 1965, only 18 days before this episode was aired, at the age of 90. As a result, his name was bleeped out for initial network showings.
Richard, seeing Dr. Morgan as a rival for Patty's love, steps aside, telling Dr. Morgan, "You are the older man." In reality, Eddie Applegate (Richard) was almost four months older than Troy Donahue (Dr. Morgan).
