When airing on Channel 4 in the UK, the final scene of the Hillbillies’ shooting was cut when Brandine got out of the car.
This is the second episode where Homer was set alight after walking into a device. The first was "Treehouse of Horror VIII".
The title is a play on the phrase "All's fair in love and war."
Bart and Milhouse listen to "Boplicity" by Miles Davis on a record player while reading Playdude.
The scene where Caan is gunned down at a tollbooth is cartoon reenactment of a scene in The Godfather in which Caan's character Sonny is killed. This scene has already been parodied in The Simpsons many times, such as when Bart is pelted with snowballs in Mr. Plow.
The music Bart's friends play in his treehouse is "Take Five" by Paul Desmond.
The music Homer asks himself to turn down is the classic 80's power ballad "Separate Ways" by Journey.
