Homer attempting to recruit companions for his security company in the Springfield church is a reference to the 1952 American western film High Noon, although the line "You all know me" is was taken from the 1975 American horror/thriller film Jaws.
The Mafia's journey to the Simpsons' house is a spoof of the opening of HBO's hit drama series The Sopranos, complete with the show's opening theme, "Woke Up This Morning" by Alabama 3. One of Fat Tony's Jersey henchmen also bears great resemblance to Paulie, one of the main supporting characters in the show.
In "Separate Vocations" it is revealed that Homer wanted to be a police officer but was rejected due to his stupidity and in "Bart the Murderer", he pretended to be a police officer. In this episode he finally becomes a police officer.
The last time Homer took the law into his own hands because Chief Wiggum was corrupt and/or incompetent occurred in "Homer the Vigilante".
Drederick Tatum's line 'I think I speak for myself, Comic Book Guy and Bumblebee Man' is an in-joke, as Hank Azaria voices all three of these characters.
When the Simpson family is following the fan early in the episode, Lisa is barefooted. However after Homer goes to plug in the Santa doll, she is suddenly wearing shoes. Then after the blackout, she is barefoot again.
