- Vallejo's CMOA: Personally threatening the son of a Canadian ambassador who abuses his diplomatic immunity, knowing full well it lies outside his jurisdiction and that his title of junior-commissioner could be suspended. Note this also happens after his two best officers quit the safety patrol to take care of the perp and his gang on their own, after he nagged them about leaving said kid alone. Vallejo would have been obligated to take Fillmore and Ingrid's badges, and he cares about the two enough to not want to be the one to do it. You know he knows what's at stake, and he goes through with it anyway. Also counts as a Big Damn Heroes moment.
Vallejo: We may not be able to officially bust you, but if you cause any more trouble in this school, the entire Safety Patrol is going to turn your life into a nightmare from which you will never wake. Am I making myself clear?Winston Cotter: ...yes, sir.
- His "they're not by themselves" beats it out though
- And how about every Chase Scene in the entire run of the series?
- The end of "A Forgotten Yesterday", in which the culprit is Out-Gambitted by Fillmore.
- Fillmore managing to beat the school mini-golf club so hard that he won every trophy they'd ever won in a row, solely because they wouldn't let him join. Yes, it was a horrible thing to do, but he managed to beat all of them in what was implied to be one day. That takes serious talent.
- And then he tops it by being man enough to admit it was terrible and make amends.
- Quite possibly the best and most clever line in the series: During "A Cold Day At X", where an algebra teacher, whose introductory scene shows her explaining to her classmates that no matter what, for any given equation the value of x will always stay the same, strongly believes that when you give them the chance and simply trust them, students will do the right thing on their own. Fillmore contests this and tells her that times have changed since she was a student at X middle school and thus stays at school overnight to ensure that a group of students don't steal the test answers. However, by the end of the episode, Fillmore realizes that she turned out to be right, at least with those kids. When the teacher talks to him the next day, she says: "So Fillmore, you had a whole day of school to yourself. Did you manage to learn anything?" Fillmore's reply? "Yeah. The value of X remains constant."
- In an early episode, Fillmore is convinced that a certain crook who's a constant thorn in the Safety Patrol's side is behind the theft of all the books in the school's library. Ingrid however becomes convinced that he's not behind it since the books were hidden in a tree house and the supposed thief is so petrified of heights he once threw up having to watch a movie about a hot air balloon. When she tries to convince Fillmore to seek another answer, he refuses because of the guy's past crimes. Ingrid, fed up with this line of thinking, calls him out on his hypocrisy by tossing the files she dug up about Fillmore's delinquent past onto his desk and leaving the room in disgust. This call-out not only gets Fillmore to change his mind about his accusation but prompts him to tell her the full story behind the soda can rocket that prompted her to dig into his past in the first place.
- Wayne in backstory. He was the only person who saw anything worth saving in Fillmore, a known hardened delinquent and crook, and offered him the choice between an unspecified but probably long period of detention and helping the Safety Patrol bust a crook. Fillmore chooses the latter and became the best Patroller the force has ever seen.
- In "South of Friendship, North of Honor", Fillmore echoes this when he tells Wayne he's too good to look the other way no matter what the corrupt Sheriff of the Safety Patrol and his flunkies do. Wayne repays this gesture by breaking out of the detention he received for investigating the theft that drives most of the episode's plot to help Fillmore when he gets into trouble going after the Sheriff by himself (despite it having been Fillmore's idea to investigate and therefore, indirectly his fault Wayne got demoted) and the pair end up jointly completely busting the Sheriff, getting him shipped off to military school with Wayne gaining leadership of the Safety Patrol with all the help he needs to clean up the school.
