The Simpsons includes a large array of supporting/minor characters:
co-workers, teachers, classmates, family friends, extended relatives,
townspeople, local celebrities, fictional characters within the show,
and even animals. The writers originally intended many of these
characters as one-time jokes or for fulfilling needed functions in the
town. A number of them have gained expanded roles and have
subsequently starred in their own episodes. According to the creator
of The Simpsons, Matt Groening, the show adopted the concept of a
large supporting cast from the Canadian sketch comedy show Second City
Television.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 in "The Principal and the
Pauper", 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. She was once a girlfriend
of fellow Simpsons character Comic Book Guy.Agnes's first name was
revealed in the seventh season episode "Bart the Fink". Before that,
the character was known as "Mrs. Skinner". In the beginning of the
series, the writers made several references to Agnes and Seymour's
unhealthily close relationship as similar to that of Norman Bates and
his mother. In "Boy Meets Curl", it is revealed that Agnes's
resentment towards Seymour may have begun even before her son was
bornâ€"during the 1952 Summer Olympics in Helsinki, Agnes competed in
the pole vaulting event while nine months pregnant. When Seymour makes
his first kick, he hits the bar, thus making Agnes lose and
subsequently crushing her dreams. However, this would contradict the
earlier episode when it is revealed that Seymour is not her birth son.
In "Grade School Confidential", it is revealed that Agnes enjoys
collecting pictures of cakes that she cuts out of magazines, a hobby
she began in 1941. However, she does not care for cake, finding it
"too sweet". In the 26th-season episode "Sky Police" she mentions that
she has a brother named Stevie. List of recurring The Simpsons characters Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
