This was the last episode filmed in New York City.
This is the eighth and final credited appearance Timothy Neufeld makes in the series. He sometimes played Tim, sometimes Tom, other times an unnamed character. Here, of course, he is playing Bill.
This is the fourth and final credited appearance Kelly Wood makes in the series. As with her earlier appearances, this time she again plays Patty's high school friend Gloria.
Richard claims to be an 'amicus curiae' to the debating team, which is a legal term derived from Latin that literally means 'friend of the court'. It speaks to a legal procedure employed by parties interested in providing input to legal proceedings, but who are not principals in those proceedings.
Martin likens the intrigue Gloria has undertaken to expel Patty from the debating club to a James Bond plot. This character, the creation of writer Ian Fleming, had by May 1965, when this episode originally aired, become a household name owing to the popularity of the movies Dr. No (1962), From Russia with Love (1963), and Goldfinger (1964) in which Sean Connery played the role of James Bond.
