Gerald and Sheila Broflovski

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.[10][16][17] He commonly wears an olive-green jacket over a purple shirt and forest green trousers. White briefs are Gerald's underpants of choice.[18] He sports a contemporary beard and separated mustache, and is almost always seen donning a pink yarmulke. When not wearing the yarmulke, Gerald is shown to have male-pattern baldness. He is a generally kind, amiable person, though at intervals he has been shown to assume a snobbish attitude that disaffects his friends and family. 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!". In "Sexual Harassment Panda", Gerald repeatedly sued South Park Elementary (which was faultless in every case), and later every citizen of South Park, showing his shameless monetary greed and disregard for civil propriety. Gerald was once seen to have a repressed gambling problem,[19] and prior struggles with a fictional form of inhalant abuse known within the show as "cheesing".[10] Gerald is, in season 20 of the show, revealed to be an internet troll. His internet alias is 'Skankhunt42', and initially, everyone thinks that Eric Cartman is, in fact, Skankhunt42. When trolling, he makes provocative statements against women, and, most notably, creates images where he "puts a dick in [women's] mouths." He always drinks red wine and listens to music by Boston when trolling. 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 wears her hair in a beehive, is overweight, and typically wears a midnight blue suit jacket over a light gray blouse, with a dark red skirt and gray stockings. She speaks with a Brooklyn accent, and appears to be of less-than-average height relative to the other female adults on the show. In the episode "It's a Jersey Thing", it is revealed that Sheila was originally from New Jersey, where she was known as "S-Wow Tittybang", and that she and Gerald moved to South Park to avoid having their newly conceived child grow up there. Apart from being briefly appointed to the fictional federal position of "Secretary of Offense" under the Clinton Administration, Sheila is a stay-at-home mother. As a result of hearing something shocking or inappropriate, she is often heard exclaiming "WHAT, WHAT, WHAT!?", saying each word in rapid succession and putting more emphasis on the last "what". Sheila has been depicted as being a huge fan of Barbra Streisand.[20]

In earlier seasons, Sheila often spearheaded public opposition to things she deemed harmful to children or to the Jewish community. 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.[21] Her outrage escalated in South Park: Bigger, Longer & Uncut when she further protested Terrance and Phillip by forming "Mothers Against Canada", which eventually instigated a war between Canada and the United States making her one of the main villains of the film. 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. This aspect has been toned down in recent years, and is more or less completely absent from newer episodes. Her relationship with Gerald varies, in the episode "Spontaneous Combustion" it is shown that Gerald suffers from periodic sexual dysfunction and erectile dysfunction which put a strain on their relationship. In "Insecurity", she and her husband used sexual roleplay to have better sex.

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.[22] In addition to her ethnicity, Eric Cartman also despises Sheila's activism, which he perceives as an attempt to inhibit anyone's ability to have fun. 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.
