Sarah Wiggum
Sarah Wiggum (voiced by Pamela Hayden) is the wife of Clancy and mother of Ralph. She met her future husband when she was arrested by him, having planted crystal meth on her to make him "notice" her. Her name is derived from an "Andy Griffith Show" gag. In that show, Andy would call up the town's operator named Sarah, and Andy would say something along the lines of, "Sarah, could you get me Aunt Bea?" In Grade School Confidential, Wiggum similarly picks up the phone and says "Sarah, get me Superintendent Chalmers" and his wife dutifully begins to dial the phone.
SarahAlthough she is often seen around Springfield, Mrs. Wiggum remains one of The Simpsons more mysterious characters. It is vaguely hinted in some of Ralph's dialogue, as well as some other sources such as The Ralph Wiggum Book that Mrs. Wiggum can be rather disturbingly neglectful towards Ralph, such as leaving the house and forgetting him by accident. Although Chief Wiggum has a very loving relationship with Ralph he often works long hours, which would leave Ralph by himself. This could explain some of Ralph's awkward behavior, but this has not been formally brought up in the series. In most cases however, she seems to be very loving towards her family. Clancy's own opinion of his wife tends to fluctuate between complete love, and possibly slight boredom and indifference.
Considering her son's awkward behavior and her husband's often dubious escapades, she can be seen as an extremely patient woman. However, she may have been driven to alcoholism, as hinted by Ralph's line, "You look like my Mommy after her box of wine." As very little has been revealed about the character, all of this is speculative of course. In the few episodes where she speaks, she sounds like a female version of her husband. Sarah has light purple, neck-length hair and a somewhat stocky build.
