Animated series depicts the ups and downs of the Simpsons, a strangely typical American family living in Springfield. The family includes Homer, a father whose head is often ruled by his stomach and who works at the local nuclear power plant; Marge is a loving, nurturing mother and wife who tries to keep peace in the family; son Bart is a smart-mouthed hell-raiser; Lisa is an intelligent and philosophical middle child who plays jazz saxophone; and baby Maggie communicates her thoughts via various sounds on her pacifier.
