The game store sign 'Sequel Stop' is a reference to the store chain GameStop.
Marge makes reference to DC superheroes Aquaman and Hawkman.
At the end of the level Kang and Kodos use the word 'space' to replace certain words, a nod to how The Smurfs would say 'smurf' instead of some nouns and verbs.
In the Xbox 360 and PlayStation 3 versions, Lisa brings together a cube, a sphere, and a triangle to make a ramp, the arrangement of EA Games' original logo. This may be lampshaded by Marge, who will note "That looks like a company logo. I think it's for a waxpaper company."
The trophy Marge collects in this level is "Hair Street Blues Hairspray", referencing the TV show Hill Street Blues.
The whole level is an obvious reference to controversy caused by the Grand Theft Auto series and other Rockstar games.
Hillary Clinton being present is most likely a reference to "Hot Coffee" controversy surrounding San Andreas.
At one point, the assumed name of the EA Executive was bleeped out for unknown reasons.
Judging by the mob members' quotes, it appears Ned Flanders is the only mob-member who is definitely aware of the mob's purpose. One theory is that, if Marge recruits someone not supportive of their cause, they instead are passionate about something else; Smithers seems to think the mob is either in support of same-sex marriage or Mr. Burns , Barney seems to view the mob as an outlet for his alcoholism, etc.
Ned and Apu are the only characters who appear in all versions
Flanders and Snake are the only mob members found in the same location in all versions.
In the PS2 and Wii version, Skinner can be recruited into the mob. He is found outside the same museum he tried to steal from in Bartman Begins.
The manual that Marge kisses at the end looks like the Strategy Guide & the manual from the Nintendo DS version.
When Children are knocked out in the Xbox 360 and PS3 version it is visualised with a cartoonish effect where The Raven flies around their heads, implying that the children have been knocked unconscious, rather than killed
In the other versions, however, you do kill the children you defeat, with them appearing in Heaven during Game Over
In the Xbox 360 and PS3 versions it is possible to kill Clancy Wiggum, Lou and Eddie once they start fighting the Mob. These deaths are not considered part of Simpsons Game continuity as Clancy remains in the Springfield hub after Mob Rules while Eddie and Lou return to the hub after Game Over.
↑EA Executive: Congratulations, Quimby. You've made Grand Theft Scratchy Day a tremendous success. Mayor Quimby: Thank you, [bleep]. Why don't we celebrate with some interns?
