The Poor Kid
Kenny's parents are arrested for having a meth lab at their home, an event documented on the reality show White Trash in Trouble. As a result, Kenny and his two siblings, Kevin McCormick and Karen McCormick, are put into the foster care system. Their caseworker, Mr. Adams, who insists on making constant jokes about the Penn State sex abuse scandal, places them with the Weatherheads, a militantly agnostic couple living in Greeley that forbids their numerous foster children from expressing any notions of certainty. Their agnosticism manifests itself in a number of peculiar ways, such as their edict that the children can only drink "agnostic beverages" such as Dr Pepper, because no one can be certain as to what flavor it is, and hypothesizing that God could be "a giant reptilian bird in charge of everything". Because of Karen's sadness and fear over their new living situation, Kenny attempts to protect and comfort her by adopting his Mysterion persona, whom she comes to see as her guardian angel.
While searching for a new target for his taunts now that Kenny is gone, Cartman is horrified to discover, through Butters' research, that he is now the poorest student in school. He fears that Kyle will start making fun of him now. Despite Kyle's lack of interest in this endeavor, Cartman begins compulsively telling poor jokes about himself to beat Kyle to the punch. Cartman complains to his mother, but she says that she is already working two jobs and cannot do more because of the economy. Wishing he were in a foster home like Kenny, Cartman frames her for running a meth lab, and despite her protests of not having done drugs in a long time, she is arrested, which is again documented by White Trash in Trouble. Despite anticipating being sent to an idyllic setting like Hawaii, Cartman is placed with the Weatherheads and attends the same school in Greeley as Kenny, where he is elated to discover that the poorest student there is not he or Kenny, but a boy named Jacob Hallory, whom Cartman takes delight in ridiculing.
After Kenny, as Mysterion, dispatches a bully who was harassing Karen, she and the other foster kids report what they saw to the Weatherheads, who torture one of the children by hosing him down with Dr Pepper for expressing such certainty. In response to the Weatherheads' cruelty, Cartman reports them to Child Protective Services. Mr. Adams comes to the children's rescue, as does Mysterion, who plants Pabst Blue Ribbon in their refrigerator, on which the Weatherheads get drunk. They are then arrested for being unfit guardians, as documented on White Trash in Trouble. Cartman is also arrested on the show for filing a false police report, and Adams urges the police to return all the foster children to their parents, as the foster care system has been embarrassed. Kenny and Cartman return home, but on their first day back at South Park Elementary, a giant Phorusrhacos-esque bird, as Mr. Weatherhead conjectured, rips open the school's roof and eats Kenny, prompting Cartman to burst into tears, once again finding himself the poorest child in school.
Behind The Scenes
In the creator commentary for the episode, Trey Parker said they went through several ideas of the foster family, rejecting ideas of sending Kenny to a rich family or a family in it for the money before settling on the "militant agnostics." This is the first episode where Kenny's siblings are named.
The episode prominently features the soft drink Dr Pepper, which commentators have noticed is often featured in the show's background.
