In the United States, Pip's father Max, a bookie, suckers a young man named George Reynold into placing $300 on a bad bet.

Max vocally rues the time he spent working as a bookie instead of being a father to his son, and returns the money to Reynold.

Very little comment here, save for this small aside: that the ties of flesh are deep and strong; that the capacity to love is a vital, rich, and all-consuming function of the human animal.

And that you can find nobility and sacrifice and love wherever you may seek it out: down the block, in the heart or - in the Twilight Zone.Jack Klugman appeared in four episodes of the original series.

In addition to this episode, he starred in "Death Ship", broadcast seven months earlier, in February, "A Game of Pool" (October 1961), and "A Passage for Trumpet" (May 1960).

S. John Launer was in three season one episodes, receiving credit in "The Purple Testament" (February 1960), but remaining uncredited in "Third from the Sun" (January 1960), in which only his voice was heard.

Rod Serling originally wanted the episode's opening to take place in Laos; it was CBS who asked for the change to Vietnam.

Starting in March 1963, actor Glenn Corbett had become a regular on the CBS series Route 66, playing returned Vietnam soldier Lincoln Case.

Unlike previous sponsor Liggett & Myers, American Tobacco did not have Serling plug their products at the end of the program.
