The Cartman family in South Park centers around Eric Cartman, primarily raised by his promiscuous mother, Liane Cartman, with a chaotic extended family including his grandparents (Harold & Mabel) and various aunts, uncles (like Uncle Stinky, Howard, Fat Bob), and cousins (like Elvin & Alexandra), all sharing similar traits; the mystery of Cartman's father was eventually revealed (comically) to be Liane herself, leading to a complex lineage.
