"We don't want a good principal! We want Mr. Clark!"
- All of Them: The mayor's aide delivers this line when a horde of unhappy students march on City Hall while the school board is meeting to vote Mr. Clark out as principal, after he's already been jailed for violating local fire safety laws.(The students are all in the town square outside, chanting "Free Mr. Clark!")Mayor's Aide: It appears Mr. Clark's students have assembled outside in an exercise of their First Amendment rights.Mayor: How many?Mayor's Aide: It looks like...all of them.
- Anti-Hero: Clark is abrasive and can be overly combative, but he's trying to improve the school.
- Anti-Villain: Mrs. Berrett is campaigning to have her son reinstated and school and get Clark thrown out, believing that it would benefit the school much more than if he were to stay. Her motives are sympathetic, but the film sides with Clark.
- Bad to the Bone: The movie's present-day sequence opens with a memorable shot of Eastside High having long slid into decay, with Guns N' Roses' "Welcome to the Jungle" blasting as delinquents throng the halls.
- Darker and Edgier: In comparison to most movies about inspirational educators. A teacher gets brutally beaten in front of a crowded lunch room in the very first scene. Things do eventually improve, though.
- Dispense with the Pleasantries: At a teachers' meeting, Clark makes abundantly clear that flattery isn't going to work on him.Mr. O'Malley: We want to welcome Mr. Clark to Eastside; we've heard so much about you, and tell you what we have done in anticipation of your arrival. Mrs. Levias, your other vice principal, and I have appointed an executive committee to oversee certain areas where we have noted a need for improvement, and Mr. Zirella, for example...Joe: You may sit down, Mr. O'Malley.
- Engineered Public Confession: Played straight, but by the antagonists in an effort to get Mr. Clark fired.
- Good Is Not Nice: It really isn't.Joe: I cried "my God, why has thou forsaken me?" and the Lord said "Joe, you're no damn good. No, I mean this! More than you realize, you're no earthly good at all unless you take this opportunity and do whatever you have to." And he didn't say "Joe, be polite".
- I'll Take That as a Compliment: When Mrs. Berrett tells the students that they're going to fire Mr. Clark and get a good principal, Sams responds with "We don't want a good principal. We want Mr. Clark!"
- Informed Poverty: How are the kids able to afford all those colorful clothes? (Of course, this is a problem with way too many '80s movies to mention.)
- Jerkass Ball: Clark. There are many moments where he's nothing but downright cruel to people, even those who are on his side and trying to help. Many of which come from either the test scores of the practice exam or his demand for everyone to learn and sing the school song upon demand. Some examples include suspending the football coach for simply picking up trash during the school song, firing the first music teacher after believing she was ignoring his request to teach the students the school song, and yelling at the second music teacher because of the way she taught the students to sing the school song, even though he's later shown to love and approve of it.
- Jerk with a Heart of Gold: While Clark tends to be a Drill Sergeant Nasty to almost everyone, including the teachers working for him, he does have their best interests in his heart and really does care for those in need. His fatherly treatment towards Kaneesha and his willingness to do everything he can to help her when she's struggling is a major example of this.
- Large Ham: Joe Clark, as portrayed by Morgan Freeman.
- Listing the Forms of Degenerates: Joe Clark does this a few times:I've got thugs, drug dealers, and deviants of all kinds trying to get into my school.
- Or...I want the name of every hoodlum, drug dealer, and miscreant who's done nothing but take this place apart on my desk by noon today.
- Non-Giving-Up School Guy: Joe Clark takes drastic measures to keep students in school and to keep undesirables out of school.
- N-Word Privileges:
- Joe Clark at a meeting calling himself the HNIC, and Mrs. Levias clarifying afterward to Mr. O'Malley, the white vice-principal, that it stands for "head nigga in charge." Though Dr. Napier claims that he is technically this, contrary to popular opinion.
- Later, while trying to pump up the students as they prepare to take the test, he tells them that people think "you're just a bunch of niggers, spics, and poor white trash", urging them to prove their detractors wrong by performing well on the exam.
- Precision F-Strike: Clark drops N-bombs on two occasions.
- Save Our Students: This movie is the Trope Codifier and was followed by several movies like it in The '80s and The '90s: including Stand and Deliver, Dangerous Minds, and The Substitute.
- Shoot the Dog: Many of Joe Clark's actions have some arguable moral ambiguity to them, from chaining and locking school doors (in violation of fire safety rules) after being told that someone from inside the school let an expelled student into the building, to indefinitely suspending a teacher for picking up trash during the school song for which everyone was told not to move.
- Shut Up, Hannibal!: All of the students do this repeatedly towards Berlett for jailing Clark, but she's too determined to shut up.
- Stuffed into a Locker: Sams, at the beginning of the movie. Then, to drive home how bad things have gotten at East Side High over the last 20 years, Sams is yelling urgently to be let out, yet a janitor walking down the empty hallway (the school day had just ended) completely ignores him.
- Suicide Dare: A rare case of someone trying to do this for the "victim's" own good. When Joe Clark runs into Sams (who had been expelled for smoking crack), who pleads to be let back into school, Joe drags him up to the roof of his building, gives him a very harsh lecture on what could happen to him if he keeps using crack, and then dares him to jump off. Sams breaks down in tears and refuses, making a promise to clean up his act, prompting Clark to give him another chance.
- "The Reason You Suck" Speech:
Napier: The truth is that for all your talk and all your "Crazy Joe" routine, what have you ever done? Nothing! You're nothing but an insignificant man! It's like you were never born! Your life hasn't made one bit of difference! And neither has mine! Want to take that to the grave?
- This is how Dr. Napier convinces Joe to take the job of principal at Eastside High:
- Clark later gives several of these himself. It's a significant part of his management style.
- Ms. Levias gives him a good one near the end, blasting him for the horrible way he treats the staff when they're working just as hard as he is.
- [Verb] This!: Just after Mrs. Berrett and the fire chief spring their Engineered Public Confession on Mr. Clark and he's being taken away in handcuffs by the police with some of his students (including Sams) looking on:Clark: Mrs. Berrett, if you think you can—Berrett: SHUT UP! You're finished! The school board is going to hear this at seven o'clock, and we are gonna vote your black ass out.Sams: *grabs his crotch* YO, BITCH! VOTE ON THIS!
- Very Loosely Based on a True Story: The movie definitely takes some liberties with the truth (see this Cracked article for more details): Clark was a very tough disciplinarian who really did clean up Eastside High, and he really did use a bullhorn and brandish a baseball bat, and he was a controversial figure for these reasons, but the movie otherwise makes up a lot of stuff. Despite the improvements Clark made, he did not succeed in getting substantial improvements in test scores, although his supporters say he would have if he had been kept in office longer.
- What the Hell, Hero?: The teachers get sick of Clark's belittling of them and extending his Jerkass attitude towards them and let him know it. Not that he really cares, at least initially. Then Dr. Napier (who claims there's been rumors of a walkout) and later, Mrs. Levias (who had just demanded to transfer to a different school) tear into him about it.
- Your Little Dismissive Diminutive:Mrs. Elliott: I would love to stay and chat, Mr. Clark, but I've a concert in New York in two weeks and I would like to be prepared.Joe Clark: What?Mrs. Elliott: Prepare. You do know what prepare means, don't you? It means ready, capable and up to your job.Joe Clark: What concert, Mrs. Elliott?Mrs. Elliott: The one at Lincoln Center. We do one every year.Joe Clark: Until now. As of this moment, your little concert is cancelled.
