[6] The two moved back to Gerald's hometown when Kyle was younger because Sheila wanted to raise her children in a small town environment,[7][8] but in "Smug Alert!

[14] Gerald is a lawyer who also serves on South Park's council as the city attorney,[15] and his role in this profession has been put on display in episodes such as "Sexual Harassment Panda" and "Chef Goes Nanners" in which a trial or legal issue plays a large part in the plot.

Examples include the episode "Chicken Pox" where it is revealed that he used to be close with Stuart McCormick when they were younger but that the two had a falling out due to economic differences or when he begins acting like an arrogant snob after buying a hybrid car in "Smug Alert!".

His antics eventually place him in the news after trolling a Danish olympian, making him one of the two main villains of the entirety of season twenty alongside Lennart Bedrager.

Sheila made her first appearance in the season one episode "Death" (where she was originally named Carol), and she exhibits several traits commonly associated with those of a stereotypical Jewish mother.

She led a group to New York City to protest Terrance and Phillip, a Canadian comedy duo whose television show's toilet humor is what she believed to be a negative influence on Kyle.

At the climax of the film, she takes her crusade against the duo to the extreme by fatally shooting Terrance and Phillip; despite her son's protests, which fulfills an apocalyptic prophecy allowing Satan, his minions, and his lover Saddam Hussein to invade the Earth.

Upon seeing Kyle taking part in a school play which involved a nativity scene, Sheila pleads with the mayor to ban the use of any religious imagery within the town that could perceived as offensive to those of different beliefs.

Cartman has even expressed his hatred for Sheila by singing a song entitled "Kyle's Mom's a Bitch" in "Mr. Hankey, the Christmas Poo" and South Park: Bigger, Longer & Uncut.

The two also accompany Ike during activities that enrich his status as a child prodigy, such as sitting with him as he read two John Steinbeck novels in one day.

Thinking he would delight Kyle by making more money, Gerald instead distressed his son by increasing the family's income at the expense of bankrupting the local elementary school.

She was seen (albeit as a corpse) in the episode "Korn's Groovy Pirate Ghost Mystery" when Kyle reluctantly allowed his friends to exhume her body so that they could use it in a Halloween prank.
