When Willow tells Dawn about her attraction to women, she uses the exact same words she did in the Season three's Doppelgangland (1999) to describe her evil vampire self: "And I think I'm kinda gay!".
The neighborhood Buffy and Spike fight in is the Desperate Housewives (2004) neighborhood set (also used in the film The 'Burbs (1989)).
The episode does not translate well into other languages. A sizable part of the humor is the interplay between Giles and Spike, laced with British idiom and Americans' stereotyped views of England; the puns based on "Randy" are meaningless in other languages. In French, "Randy" is translated to "Candide", possibly a reference to the Voltaire novel. Buffy's assumed name "Joan" is left as "Joan" in French, and the reference to Joan of Arc ("Jeanne d'Arc" in French) is mostly lost. Dawn's reference to Xander as "Alex", a more common shortened form of "Alexander", lacks significance in the French translation because he has been named Alex in France since "Welcome to the Hellmouth".
This is the first time Michelle Branch appears in a TV series singing 'Goodbye To You'. The second time is on Charmed (1998), another WB network show featuring witches.
Spike's description as Randy of Giles' "mid-life crisis transport" matches his actual current car, a red BMW convertible acquired in Real Me (2000).
