Selma Bouvier Terwilliger Hutz McClure is Marge Simpson’s older sister and Patty’s identical twin. Like Patty, she clerks at the Springfield DMV and hates Homer Simpson with a passion. Although a desperate desire for companionship has led her into several ill-fated marriages over the years, even Selma has her limits. From now on, she has vowed to marry only for love. Or possibly for money. Or out of boredom. Or any combination of the three.
