"The Death of Eric Cartman" is the sixth episode of the ninth season of the American animated television series South Park.
When she arrives, the boys help her unload her groceries, but Cartman remains behind, eats all the chicken skin, and goes home to sit on the toilet and read comic books.
Enraged, Stan, Kyle, and Kenny decide Cartman has finally crossed the line and start to ignore him.
Cartman goes home and mistakenly believes that the toilet is his body when he sees a box being carried out of the house by plumbers.
Cartman draws up a long list and delivers gift baskets to all his victims, including Sally Struthers, Scott Tenorman, and Kyle's synagogue.
To make sure, Butters is taken to a mental institution and subjected to a series of tests (one of which includes a violent anal probing).
Trey Parker says on the DVD commentary that he got the main idea for the episode while hiking on vacation in Tasmania, Australia.
