Synopsis by Perry Seibert
This typically irreverent episode of South Park involves an interesting medical problem for Eric Cartman. After managing to get a picture of Kenny's posterior on milk cartons around the country, Cartman is unable to laugh because nothing else is as funny. However, there are strange ramifications for the prank when people come looking for the child on the milk carton. "How to Eat With Your Butt" first aired November 14, 2001.
