In the final scene, James Caan parodies his death scene from The Godfather (1972). This is the second time that scene has been reference by The Simpsons. In the previous episode 'The Simpsons: Mr. Plow (1992)(TV)', Bart is the victim, and he is ambushed by students using snowballs. Another of his scenes is parodied in 'The Simpsons: Strong Arms of the Ma (2003)(TV)', Marge beats up a criminal, in a shot nearly identical to when Sonny beats up Carlo.
The title is a reference to "all's fair in love and war".
It is revealed that Agnes Skinner is bald and her hair is a wig.
