* AlternativeJokeInterpretation: When Milhouse talked to Bart about "walking in on just one [parent]," was he referring to one parent masturbating, or walking in on one parent sleeping around with another partner? From what we've seen of Milhouse's parents post-divorce, both could apply equally.
* CharacterRerailment: Homer lying about Greystash's death to Lisa is considered one of the best post-SeasonalRot Simpsons scenes because it reminded viewers that Homer could be a caring, if misguided father and that Lisa, despite her intelligence, still had childish interests appropriate to her age.
* HeartwarmingInHindsight: Nelson and Bart must have worked things out after the events of this episode, because by the following season's "The Debarted" Bart will refer to Milhouse and Nelson respectively as "my best friend" and "my other best friend."
* HoYay: This episode is full of it, between Bart and Nelson.
* UnintentionalPeriodPiece: The B-plot is a reference to the release of ''Literature/HarryPotterAndTheHalfBloodPrince'' and its associated ItWasHisSled viral spoiler in 2005.
