When applying for a preschool for their non-existent child, Daphne and Niles scroll through a book of names and pick one at random as a placeholder. One name they choose is "Bob," but when Niles says "Bob...Crane" aloud he immediately says he will need whiteout. Probably obvious to many viewers at the time, Bob Crane was the popular actor in the late 60s TV series "Hogan's Heroes" who played the titular Colonel Hogan. However, his legacy would sadly be one of drugs, illicit sex, and dying under mysterious circumstances. When this episode aired in 2003, Bob Crane's sordid story had just been brought to the big screen in the film "Auto Focus (2002)."
David Ogden Stiers's character of Major Winchester on "M*A*S*H (1972)" has been considered the inspiration for the creation of Frasier on "Cheers (1982)." Both were high society doctors surrounded by blue collar comrades. Interestingly, Winchester was from Boston while "Cheers" was set in Boston.
Martin tells Roz about the affair that Hester once had, an affair which was first revealed in the episode "Beloved Infidel" (1993).
The two songs sung at the end of the episode were written by late 19th-century English song writers Gilbert and Sullivan. The first--sung by Frasier, Niles and Leland--is "Modern Major-General" from "The Pirates of Penzance." The second, sung by Frasier and Niles, is "On a Tree by a River" from "The Mikado."
