Cancelled

"Cancelled" is episode 704 of the Comedy Central series South Park. It originally aired on March 19, 2003.

In terms of production, this is the 100th episode, though "I'm a Little Bit Country", was actually aired as such. Its production was alluded to in a joke in the episode.

Plot
This episode begins in a manner very similar to the first episode, "Cartman Gets an Anal Probe", with  Cartman arriving and talking about a dream where he was abducted by aliens. When the children realize this, they and Chef decide to do something about the anal probe Cartman has; they first see a proctologist, then a scientist. They discover the probe is sending off pictures of Earth into space; then a group of Visitors show up, and the children and Chef flee. The children are ultimately abducted, though.

The kids wake up on the ship, and meet Najix, an alien who looks like Stan's dad, explaining to them that he chose an appearance that would be most pleasing to them. The disappointed children say it's like the movie Contact which "sucked." He shows his true form, a terrifying monster, so the children have him go through a series of transformations, mostly of celebrities, until Cartman suggests "a taco that craps out ice cream". Najix then explains he and the other aliens make a reality show called Earth, which Chef and the scientists discover at the same time on Earth; they proceed to tell everyone, which leads the alien network heads to cancel the show and prepare to destroy the Earth.

The boys go to Planet Fognl to meet the alien heads, who are "Joozians", a species that control all media in the Universe. The aliens don't listen to the boys, but insist on taking them to lunch, a "hekma"(titty) bar, then get a prostitute's hotel room. The two Joozians then, very drunk and high on "blach", begin sucking on each others' "jagons" and licking each others "Quarth." Kenny takes a picture of it, and the boys then blackmail the aliens with it. The Joozians agree to erase everyone's memory of the truth about Earth, then send the oblivious boys back to their own planet. Kenny still has the picture, and though no one can remember what it is, Chef tells Kenny to keep it, as he feels sure it's something very important.

Trivia

 * The "Joozians" who run the universe's media are parodies of Jews and the charge that Jews secretly run the media; they are shown with stereotypically Jewish appearance (such as their very large noses), use words that sound like Hebrew and when Kyle (who is Jewish) samples some of their food and likes it the aliens claim that he seems to have "Joozian ancestry" to which Cartman replies "Tell us about it."
 * Forms that the alien takes on: Randy Marsh (Stan's dad), Santa Claus, Frank Sinatra, Michael Jordan, Don King, George Burns, Saddam Hussein, Jimmie Walker, Missy Elliot and Mr. Roarke and Tattoo from Fantasy Island.
 * The Joozians congratulate the boys for having their show (Earth) make it to 100 episodes. "Cancelled" is however only the 97th episode of South Park, the true 100th episode is I'm a Little Bit Country, in which Stan's Dad tells the viewers it is the 100th episode.
 * In syndication, the reference to the Joozians' apparent oral sex was cut out.
 * The man with the girl in the 'earth' video resembles Matt Stone.
 * When Cartman woke up in the green goo on the alien space ship, he screamed, "I'm trapped inside Helen Hunt's ass!".

References to Pop culture

 * Sounds from the game DooM are used in this episode (the door open and close sound)
 * The movie Contact is parodied.
 * The alien construction (and tearing down) of the Earth is a reference to Douglas Adams' The Hitchhiker's Guide to the Galaxy.
 * The alien chase scene in the first act parodies the archetypal chase scene in The Dukes of Hazzard. A caricature of Boss Hogg can be seen on a billboard during the chase scene, with the words "Eat big beef." The alien giving chase also impersonates the cackling laugh of Sheriff Roscoe P Coltrane.
 * The aliens' car is a Buick LeSabre, complete with a mock Buick emblem.
 * The plot of the episode also parodies The Truman Show.
 * According to the shape-shifting alien, each planet has only one species living on it. This is a reference to popular science fiction works such as Star Trek in which each alien species seems to exist on a world without (or at least extremely limited) additional animal life.
 * The scientist trying to help the boys and Chef looks like a South Park version of Jeff Goldblum. In a reference to Independence Day, when puzzling out alien technology and action, Jeff Goldblum's character follows unlikely chains of thought to come to conclusions that, curiously, turn out to be exactly correct. The scientist could also be "Xeno"  (web site).  Scientist and musician Xeno did some sound engineering work and was paid by the studio. During this interaction, it is believed that the authors became aware of the site. Compare the photo of Xeno to the scientist.
