Who is Agnes Skinner?
Agnes Skinner is the mother of Principal Seymour Skinner. Cantankerous and possessive, she houses him, dominates him and belittles him at every opportunity, treating him as an eternal child. An amusing detail: her first name, "Agnes", is only revealed late in the series; before that, she was simply "Mrs Skinner".

A smothering hold over Seymour
The whole mother-and-son relationship rests on a smothering domination, which the writers colored very early on with an openly acknowledged unease — a fused relationship explicitly compared to that of Norman Bates and his mother in Psycho. Agnes also hates the teacher Edna Krabappel, out of jealousy over her son's feelings for her.

An Olympic champion with a surprising past
Behind her air of an embittered old lady, Agnes hides an unsuspected past: that of a former Olympic pole vaulter. The series reveals that she competed at the 1952 Summer Olympics in Helsinki... while she was nine months pregnant with Seymour — a kick from the fetus costing her the victory. Which goes some way to explaining her stubborn resentment toward her son.
