They are first seen inside Cartman's grandmother 's house at the beginning of the episode, while Liane introduces the family to The Boys , for some reason she didn't introduce these two, so their names are unknown, they are probably Eric 's uncle and aunt . They later appear at the end of the episode in prison with the rest of the family singing to Charles Manson . Only one of them has a line in the episode.
They later appear in "Cartmanland " at Mabel Cartman's funeral.
Cartman's first unnamed relative (probably aunt) wears a light green long-sleeved shirt and has blond hair, and Cartman's other unnamed relative (probably uncle) wears a white shirt under a dark pink coat, black pants, and black shoes. Like the rest of the Cartman family they are very obese.
