His mother, Marge (voiced by Julie Kavner), was once a thoughtful woman. After marrying Homer, she gradually adapted to the routine of housewife life. Bart (voiced by Nancy Cartwright) is the eldest son in the family. Bart, who is naughty by nature, often likes to play some pranks, so that he often gets into trouble. Sister Lisa (voiced by Yeardley Smith) is a very smart child, and she is also a vegetarian, Buddhist, and jazz music. The little girl, Marge, is a child who never grows up.
