It's a Jersey Thing/Trivia

Trivia

 * This is the first episode to be announced immediately following another's airing since "The Passion of the Jew"; all other episodes since Season 9 have been announced on a Friday or a Monday. However, it is not the first to release a preview clip right after the previous episode. The episode "200" had a preview clip released for it the day after the episode before it, "You have 0 Friends", was aired (even though that preview clip didn't make it into the final cut).
 * This episode reveals that Kyle's conception took place in New Jersey
 * In the episode, it shows Stephen Stotch, Dog Poo, and Eric Cartman being sexually violated (or raped) by a monstrous Snooki.
 * In this episode, the monstrous Snooki appeared saying, "Snooki" and "Snooki want smush smush." This was probably because of the Jersey Shore cast using the term "smush.'"
 * The working title for this episode was "New Jersey". This was later changed to "It Came From Jersey" and was later finalized as "It's a Jersey Thing".
 * When Osama bin Laden was watching the peace video Randy sent him, it showed the Jersey Shore intro beginning with Snooki in a monstrous form.
 * This episode marks Dog Poo's second speaking role (first was in "Professor Chaos").
 * Bill and Fosse return in this episode.
 * The bartender from Skeeter's Bar returns from the season 13 episode, "W.T.F."
 * Sheila Broflovski is revealed to be from Jersey in this episode.
 * This marks the second episode so far where Cartman honestly thanked Kyle, the first being "Le Petit Tourette."
 * This is the second time that Kyle made Cartman cry like a baby since It's Christmas in Canada, however Kyle threatened to break Cartman's face in if the fatass continues refusing to listen to Kyle's truth.
 * When Kyle shaved his eyebrows while changing into his Jersey look, they are shaped like Cartman's eyebrows, only backwards.
 * How Sheila described that people from Jersey will always believe people think they are cool despite how obvious they are hated, is the same thing Cartman believed about himself in "Breast Cancer Show Ever". As well as the Harley Riders in "The F Word".
 * According to "Jared Has Aides", it takes 22.3 years for a tragedy to become funny and acceptable to laugh about. Stephen Stotch says that the 9/11 victims' families' feelings still matter for another ten months (which would be a month short of the ten year anniversary). So while their feelings may not matter after that time, it is still not acceptable to make fun of them for another 12.3 years.
 * This is the second episode in which Osama bin Laden has been killed with the first being "Osama bin Laden Has Farty Pants".
 * The video Randy gave to Osama bin Laden is labeled "The Shaw Redemp" which is a reference to Frank Darabont's acclaimed film The Shawshank Redemption which is based on a Stephen King novella Rita Hayworth and Shawshank Redemption in the book Different Seasons.
 * The weapons that are passed around to the townspeople of South Park to defend themselves from the Jersey invasion are 1860's style rifled muskets and Henry repeaters. This is an obvious reference to the episode "The Red Badge of Gayness" in which most the men in South Park took place in a Civil War reenactment that went out of control. Considering that The Red Badge of Gayness is almost 11 years old. This would make it one of South Park's oldest original references to date.

Goofs

 * When Cartman was telling Stan how to get rid of his new neighbors in Sizzler, one of Kenny's french fries completely disappears.
 * When the town was shooting the Jersey folk on top of the wall of rubble you could see Grampa Marsh at the very end of the line shooting, however he isn't confined to his wheel chair.
 * When an image of Sheila's past is shown, you can see she is wearing a Christian cross; whilst this may have been done to match her Jersey-like appearance, it ignores the obvious fact that she is Jewish. Although this could also mean that she married into the Jewish religion and was originally a Christian.
 * Osama had already been killed in "Osama bin Laden Has Farty Pants"

Cultural References

 * The episode strongly references the MTV reality series Jersey Shore, as well as referencing The Real Housewives of New Jersey.
 * The bathroom scene is a parody of the bathroom transformation scene in Teen Wolf.
 * The Shawshank Redemption is barely but readibly labeled on the jersey tape.
