Agnes Skinner (voiced by Tress MacNeille) is the mother of Principal Skinner and first appeared in the first season episode "The Crepes of Wrath" as an old woman who embarrassingly calls her son "Spanky". However, as episodes progressed, the character turned bitter. She is very controlling of her son and often treats him as if he is a child. She hates Edna Krabappel due to her son's feelings for the other woman. Agnes has married four times. Several Springfield residents (including the Simpsons) are afraid of her. When "the real Seymour Skinner" arrives in Springfield, Agnes ends up rejecting him in part because he stands up to her, but also because unlike Skinner/Tamzarian, her biological son is independent and does not need her anymore, while Skinner immediately reverts to a good-for-nothing without her.
