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.
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.
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.
