Kim, Kourtney and Khloé Kardashian are three women that star on the show Keeping Up with the Kardashians. They first appeared in the episode "The Tale of Scrotie McBoogerballs".
Like in real life, the Kardashian's show seems to only revolve around the three girls talking to the camera about how rich they are and what they are going to buy that day.
Despite the shallowness of the series, it's a complete hit, and even Butters Stotch finds himself enamored by the three girls, especially Kim, who he states he wants to "Jump on her belly".
When the boys read The Catcher in the Rye for a class assignment, they find it horribly disappointing as a "controversial" story, they opt to write their own The Tales of Scrotie McBoogerballs and proceed to make it as vulgar as possible for the sake of vulgarity. However, afraid of getting in trouble when their parents find it, they switch the blame to Butters, who gains instant celebrity status, as the book becomes a massive hit. Butters proceeds to then write The Poop That Took a Pee, which is a childish sequel to the previous book, but like the first becomes an instant success.
However, the second book somehow causes a reader to believe to kill all the "phonies" which to him mean to kill the Kardashians . He then travels to where the show is being filmed and brutally shoots all three girls, along with Bruce and Kris Jenner, with a 12-gauge pump-action shotgun.
This causes Butter's career as an author to abruptly end, and both his book and the book that the boys wrote both become banned. He is left completely devastated over the fact that they were murdered because of him.
In "The Hobbit", it has been confirmed that they have somehow been resurrected, as Kim Kardashian is now Kanye West's fiancée. It is also revealed that Kim Kardashian apparently has many striking similarities to a hobbit, in terms of appearance and lifestyle. Kim is also criticized by Wendy Testaburger as a product of Photoshop. According to her, Kim Kardashian is a short, overweight "Hobbit", causing her to be called "jelly" by Mr Mackey, and threatening to send her to "Jelly School".
"This is a fantasy, you moron! You ever heard of Photoshop?! Kim Kardashian is a short, overweight woman who manipulates her image and makes average girls feel horrible about themselves!" This is how Wendy refers to Kim.
Caitlyn Jenner (formerly Bruce Jenner), made her debut in the beginning of Season 19, and was one of the main focuses in the season. A running gag throughout the Season was Caitlyn Jenner running over and killing lots of people with her car, referring to when Bruce Jenner had a car accident in June 2015. The character somehow revived and came back into South Park as Caitlyn Jenner.
- It is unknown how or why the girls managed to come back, however it appears that many of the celebrities who have appeared in South Park and been killed (such as Britney Spears, Bill Gates, Rob Reiner, George Lucas, and Steven Spielberg), have a Kenny-esque ability to cheat death.
