August 13, 1997
Stan, Kyle, Cartman, and Kenny are four foul-mouthed little boys from a Coloradan hick town. During a typical morning waiting for the school bus, Kyle's baby brother, Ike, gets abducted by aliens — who are connected with several mysterious cow mutilations and abducting Cartman and putting a communication probe up his butt
"Cartman Gets an Anal Probe" contains examples of:
- Aliens Steal Cattle: Turns out the aliens were trying to communicate with the cows. The mutilations were just a mistake from one of the less experienced aliens.
- Allergic to Love: Stan vomits whenever he has affection for Wendy.
- Anal Probing
- Big Brother Instinct: As much as Kyle is annoyed with Ike, he desperately wants to save him.
- Black Helicopter: A farmer claims to Officer Barbrady that he's seen them flying around. When a whole bunch of them pass by, Barbrady claims it was just a pigeon.
- Cluster Bleep Bomb: Kyle's rant to the aliens.
- Crush Parade: Kenny is killed by a laser beam, stampeding cattle, and Officer Barbrady's car.
- Early-Installment Weirdness: This was the only episode to have actually been photographed with real paper cut-outs, though some scenes like when the satellite dish comes out of Cartman's ass were animated using the digital method when the pilot was reworked for television. The only other episode using the original technique was a short scene from "An Elephant Makes Love to a Pig" (that actually was a cut scene from this episode, where the boys talk to Pip).
- In an example of color schemes not yet being set, Bebe wears a green jacket instead of her usual red one, and Red is shown to be wearing purple.
- Mr.Hat has no visible eyes, while Mr. Garrison has a slightly different face and glasses.
- Two Hasidic boys (one later identified as "Jason") can be seen as minor characters in the cafeteria, and appear in other episode. "Mr. Hankey the Christmas Poo" and other later episodes identify Kyle's family as being the only Jews in South Park, which is then retconned itself in later seasons.
- As mentioned in "Off Model", the unaired version of the pilot didn't have Wendy or Pip visible in the classroom as students, but two other girls that were never seen beyond that part. Bebe was also not visible beyond her cameo in the bus scene.
- Farts on Fire: Cartman's anal probe causes him to fart fire, which at one point burns Pip and Mr. Kitty.
- In the unaired version of the episode, the fire came from Cartman being forced to eat all the hot tamales that Chef gave the boys.
- Flat Earth Atheist: Cartman remains firm in his beliefs that everything that happened to him was just a dream, even in spite of the fact that everything seems to be happening to him, specifically.
- Freak Out: "WHERE HAS THAT FINGER BEEN, KYLE?!?!?
- Funny Background Event: In the unaired version of the pilot, Dogpoo (the dirty, Pigpen-esque kid) can be seen at the playground digging in the snow to roll around in the dirt underneath.
- Mistook the Dominant Lifeform: The aliens consider cows to be the most intelligent species on Earth.
- Oblivious To His Own Description: When Cartman sees crop circles that resemble his face, he assumes they look like Tom Selleck.
- The Other Marty: The unaired version of the pilot had the female characters voiced by Karri Turner, as opposed to Mary Kay Bergman. Turner was let go for the final version, as the creators felt that her voice wasn't distinct enough for the characters they'd wanted her to play.
- Off Model: The animation in this episode switches from the crude, construction-paper cutout style to the computer-generated style, as Trey and Matt patched together the original pilot with some new and alternate scenes that weren't in the original version.
- Due to the classroom scene being changed for the finished version, Wendy and Pip abruptly appear out of nowhere when Cartman farts fire. In shots before this (and in the full scene in the unaired pilot), their seats were taken by an unnamed blonde girl and a second red-haired girl.
- Take That: Kyle gets Ike to jump from the alien ship by telling him to do an "impression of David Caruso's career".
- What Could Have Been: The longer version of the pilot shows that Cartman was to have a father and younger sister. An early version of Nurse Gollum also appeared, named "Nurse McSchwartz" and lacking the dead fetus at the side of her head. And Kenny shows up in the end.
