It's a Jersey Thing

"It's a Jersey Thing" is the ninth episode of the fourteenth season of the American animated television series South Park, and the 204th episode of the series overall. It premiered on Comedy Central in the United States on October 13, 2010. In the episode, New Jersey is rapidly taking over the nation one state at a time and their next stop is South Park. As the Jerseyites spill into Colorado and approach South Park, the town stands strong against the onslaught.

The episode was written and directed by series co-creator Trey Parker. In its original American broadcast on October 13, 2010, "It's a Jersey Thing" was watched by 3.253 million viewers, according to the Nielsen Media Research. It was the highest-viewed scripted show. It received a 1.9 rating/5% share among adult viewers between ages 18 and 49. 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 was not used in the final episode).

The episode revolves around the invasion of South Park by the Jerseyites, based on characters from the MTV reality show, Jersey Shore and from The Real Housewives of New Jersey on Bravo. Footage from the opening credits of the MTV series is used.
