Agnes Skinner

Agnes Skinner is the strict and bitter mother of Seymour Skinner. She is very harshly controlling her son and treats him like a mother would do to a small child, once grounding him because he did not say who was at the door after answering it. She hates Seymour's choice of women, especially with Edna Krabappel. Agnes has married a total of four times, once with Skinner's father, Sheldon Skinner, and following Sheldon's death, she then married three more times, each time to a tow truck driver. Several Springfield residents are afraid of her.

In "All's Fair in Oven War" it's revealed that she wears a wig, as she dumps it into Marge's mixing bowl. In "Ned 'N Edna's Blend", she asks Seymour if he used her wig glue to patch his shoes again.

Agnes shares an unhealthy relationship with her son, which often borders on psychosis. Examples include Agnes covering up "her half of the television" with cardboard to spite Seymour. When Seymour was out of the house, Agnes phoned him regularly demanding to be taken out of the bath, shielded from the glare of car lights on the street, and other such petty requests. She hid his car keys as a punishment for his talking to a woman on the phone. Seymour himself is very obedient and almost distressingly physically and emotionally close to her (for example, when Edna agreed to marry Seymour, Agnes murmured under her breath. Agnes Skinner's catchphrase is "Seymour!" often used to snap her son's attention. She also uses him as a slave for her own bidding as evident from the quote "Why couldn't you have died instead of the Car?".

Some of Agnes' resentment to Seymour may have derived from even before Seymour was born - during the 1952 Summer Olympics in Helsinki, Agnes competed in the pole vaulting event while she was 9-months pregnant. When Seymour makes his first kick, he hits the bar, thus, making Agnes lose and subsequently crushing her dreams; this is probably why she is so harsh on Seymour.

Her husband Sheldon Skinner resembles Seymour Skinner. Agnes has also claimed that she was married to three tow truckers. She also briefly dated the Comic Book Guy, before he was arrested for having a secret room full of illegal videos. He asked her if she would wait for him till he got out of jail but she refuses, saying that her bones are half dust. She also revealed that she once had an affair with Mr. Burns.

Agnes Skinner had several affairs with several men, including Comic Book Guy and Gary Chalmers.

In "Yellow Subterfuge", Agnes gets stabbed in the back and dies. However, this was revealed to be a farce staged by Homer and Bart.

Agnes can be seen with a mustache in Lisa's dream.

During the second segment, Skinner mentions that his mother hid his car keys as to punish him for talking to a woman on the phone.

Agnes is burned at the stack at the beginning of the final segment, due to being a witch, before that she dies, she says to her son, "See you in Hell, Seymour". To which Skiner happily said goodbye.

Although, with no continuity, Agnes is dropped to her death from many stories up in Treehouse of Horror XI, when Homer is attempting a good deed.

After Jonathan Frink Sr. takes Skinner's spine, Agnes is not amused by it.

After she refuses to give Bart, Lisa, Milhouse, and Nelson candy, they pulled a prank by egging her house for revenge.

In the episode "The Principal and the Pauper", Agnes' biological son, the real Seymour Skinner returns to Springfield from war. Agnes, not happy with her new living situation with her biological son, travels to Capital City to take back Armin Tamzarian. She and other Springfieldians, who have grown to like Tamzarian, force the real Seymour Skinner out of Springfield, tying him to a freight train cart headed out of the town. She apparently was displeased with her biological son even before her return, as it was implied that she was fully aware Armin wasn't actually her son, yet played along with Armin's con, even telling him where his bedroom was.

Prior to The Simpsons Game Agnes went to see a Jersey Boys concert and was sitting in front of Dewey Largo, her hair was blocking his view and later wanted to sue for it.

Agnes saw the Bullies at the Museum and tried to call 911 but they blocked her number.

Afterwards she saw Bart and thanked him for putting Seymour in jail, saying he needed more discipline. When Agnes saw some people signing up at the Duff Brewery, she said that they would kill themselves after eating too much.

Agnes saw Largo with his Lawyer who wanted to sue her, they went to court off-screen. Agnes saw Bart later and said that she wish Seymour helped her win eating Contests.she heard later Mr Burns in his sleep planing to cut down the trees. Agnes saw Bart later to say that Bart wanted a medal for saving the Trees.

She later met Snake, Agnes said she didn't have any money Snake then wonders why does everyone always assume that hes gonna rob them Agnes tell him because he's a Professional Criminal.

Agnes saw the Dolphins attacking Sea Captain at the pier. She went to the Mall then a Alien steals her parking a Spot then Lard lad Appears out of nowhere and steals her purse.

She thanks Bart for Stopping the Dolphins and says that he Conquered Sideshow Bob but the real hero was a rake. She says that Lard Lad needed a role Model.

And she is reprised by Tress MacNeille in the English dub and Reiko Suzuki in the Japanese dub.
