Skinner's actions often involve ensuring the school has adequate funding. His constant, desperate, and usually ineffective attempts at maintaining discipline are an effort to receive good reviews in the frequent inspections of his very strict boss,
Superintendent Chalmers, who makes no effort to hide his disapproval of Skinner. These inspections usually turn awry due to
Bart Simpson's elaborate pranks, which play off Skinner's desperation for order. Over the years of pranks and inspections, though, Skinner has developed a
love–hate relationship with Bart;
when Skinner was fired and replaced by
Ned Flanders, Bart found pranks less meaningful, due to Flanders' lax approach to discipline, while Skinner missed his constant battles with Bart. The two bonded during this time and Bart made an effort to get Skinner reinstated in the school. One of Skinner's defining traits is that he has served as a
Green Beret sergeant during the
Vietnam War, where he was captured by the
Viet Cong at the
Battle of Khe Sanh and spent three years as a
prisoner of war. Seeing his entire platoon devoured by an elephant was one of the many things that led to the development of his
post-traumatic stress disorder. He is also quite bitter about the treatment that he and other Vietnam veterans have received upon returning from the war. Skinner is a highly skilled combatant, particularly hand-to-hand, and demonstrates his abilities in several episodes. Skinner often seems weak-willed and easily suppressed, but frequently uses his military command experience to get real respect and discipline. When he and the students are snowed-in at the school, he treats them like his squad to control the chaos temporarily, before they mutiny. Although Skinner likes to maintain the image of a strict disciplinarian, he is often weak-willed and nervous and has a very unhealthy dependence on his mother, who still lives with him, constantly torments him and nicknames him "Spanky". Aside from a short-lived relationship with
Patty Bouvier, most of Skinner's love life is focused on
Edna Krabappel. He and Edna kiss in Martin's playhouse after they are invited to a birthday party, and they are witnessed by Bart. He loses his job along with Edna when Superintendent Chalmers is advised of their romance by
Chief Wiggum, after which Skinner and Edna lock themselves in the school with Bart demanding their jobs back. After Skinner is reinstated, he and Edna date for several more years and become engaged, but later cancel the wedding. Edna has shown she does want to continue dating Skinner, but first wants him to commit to her—namely by not letting his
mother, with whom he still lives, control him anymore. The controversial season 9 episode "
The Principal and the Pauper" heavily alters Skinner's backstory, revealing him as an impostor. Born as Armin Tamzarian, he has been a troubled orphan from Capital City, who is forced into the US Army during the Vietnam War. There, he serves as a
Green Beret under Sgt. Seymour Skinner, whom he comes to idolize and befriend. When the sergeant is reported missing and presumed dead, Armin returns to Springfield to inform Skinner's mother, Agnes, but she deliberately mistakes him for Seymour, so he assumes his identity and follows Skinner's dream of becoming a school principal. The real Seymour Skinner (voiced by
Martin Sheen) is alive after all, and briefly returns to Springfield to take his rightful place as Springfield Elementary School principal, but proves hopelessly unpopular and the Springfielders run him out of town on the railroad.
Judge Snyder grants Tamzarian Skinner's "name, and his past, present, future, and mother", and decrees that no one will mention his true identity again "under penalty of
torture" (although Lisa uses the real name in the episode "
I, (Annoyed Grunt)-Bot"). A clip from the episode is used in season eleven's "
Behind the Laughter" as an example of the show's increasingly "gimmicky and nonsensical plots". The continuity of the series appears to have been
retconned to the original story of Seymour Skinner in the 2010 episode "
Boy Meets Curl", as he is clearly shown to kick Agnes Skinner in utero, establishing him as Agnes' biological son after all. This is further declared in the Season 29 episode "
Grampy Can Ya Hear Me" where a teenage Seymour is shown living with Agnes before going off to college. Another part of Skinner's backstory is revealed in the season 21 episode "
Pranks and Greens". When Bart plays numerous pranks on teachers at school, Skinner reveals to Bart that there was a student who was an even better prankster than him. Bart is eager to discover the prankster's identity. Later,
Groundskeeper Willie tells him the story: years ago, the school had a swimming pool and team, with Willie as their coach. Skinner was a more easygoing principal, but it all changed when student Andy Hamilton filled the pool with worms and locked Skinner inside it for a long weekend (Monday being a teachers' holiday, Skinner was not rescued until Tuesday morning). This experience has caused him to become serious and almost merciless in his approach to rules, even going as far as to shut down the pool and demoting Willie, the swim teacher, to groundskeeper. ==Character==
