Magnum's comment about calling Ida Lupino if he is unable to contact Carol or the district attorney is a jokey reference to the 1972 television movie "Women In Prison," in which Ms. Lupino played a female parole officer who goes undercover to investigate problems at a women's prison. The in-joke is furthered by the fact that the director of the Magnum episode, Bernald Kowalski, also directed "Women In Prison."
