Go To

Most of the faculty members of Jerome Horwitz Elementary who help Mr. Krupp run the school under a single goal: to make school life for their students as difficult, boring, and miserable as possible.


    open/close all folders 

    Shared Tropes 
  • Adults Are Useless: More shown in the animated series, most of them are rather incompetent.
  • Advanced Ancient Acropolis: In the Epic Choice-O-Rama special, George and Harold stumble across Teacherville, an underground and technologically advanced society where the teachers and faculty members reside in. Every member, from recurring to minor, is shown to reside there.
  • Asshole Victim: They often find themselves as the victims of George and Harold's pranks. But given their track record of tormenting kids, you actually want to see them suffer.
  • Child Hater: In the books, they have a certain level of disdain for children which motivates them to make school-life harder for them.
  • Chuck Cunningham Syndrome: The following faculty members were omitted from the animated versions of the series, most likely because of their lack of necessity and character depth in the overall storyline: Miss Fitt, Ms. Guided, Mr. Rustworthy, Ms. Dayken, Miss Singerbrains, Ms. Anita Calculator, Ms. Zurry, Miss Labler.
  • Color Motif: Most of them wear purple; befitting as their school team is named after the Purple Dragon Sing-A-Long Friends.
  • Evil Makes You Monstrous: As if being sadistic teachers wasn't enough, the faculty members end up becoming more wicked, destructive, and diabolical once they turn into the main villain of a given book/episode.
  • Flat Character: In the book series, most of the faculty members don't have very memorable or distinct personalities apart from hating children.
  • Laser-Guided Karma: Happens quite a lot of times throughout the book series as punishment for their mistreatment of George, Harold, and the students in general.
    • In Book 2, they openly celebrate the boys getting suspended. At the end of the story, they end up having detention and are forced to write lines on the chalkboard by order of the boys who became principals for the day.
    • In Book 4, they openly taunt the boys for being forced to miss out on a pizza-themed field trip and throw them a box of crusts for them to eat. They get turned into "snowmen" as part of the boys' pranks.
    • In Book 11, a majority of them are ecstatic with the idea of separating George and Harold by their grade levels and destroying their friendship as a result. Thanks to the boys traveling through time and unintentionally creating two versions of them via time paradox, the faculty members strip themselves of their underwear, begin acting as if everything was a dream, and are then sent to the Piqua Valley Home for the Reality Challenged.
    • In Book 12, the faculty members take full advantage of Mr. Meaner's drug that brainwashes the students into becoming mindless servants for them to exploit to their hearts' content. The heroes turn this against them by disguising themselves as an adult and ordering the children to prank the faculty and commit property damage.
  • "Miss X" Pun: All the teachers in Jerome Horwitz Elementary have names that follow the "title + fragment" format that forms a punny name when read out: Ms. Ribble ("miserable"), Mr. Fyde ("mystified"), Mr. Meaner ("misdemeanor"), Mr. Rected ("misdirected"), etc. As a bonus, the teachers' full names also form a different, equally unflattering, pun.
  • Monster of the Week: Several of the faculty members have served as the main villain/monster of a given storyline.
  • Nice Mean And In Between: In the animated adaptations, the faculty members fall into the three categories rather than being completely mean like in the books. There's the "Nice" (Mr. Ree, Jerry Citizen, Edith the Lunch Lady), the "Mean" (Ms. Ribble, Mr. Meaner, Mr. Rected, Ms. Herd) and the "In-Between" (Ms. Anthrope, Mr. Fyde, Ms. Yewh, Dr. Mentor).
  • Put on a Bus: Most of the faculty members are absent in season 3 of the animated series. Justified, as many of them would not need to be involved in a summer camp setting. The only members who do appear are Mr. Meaner, Ms. Anthrope, and Mr. Ree.
  • Sadist Teacher: A majority of them come off as this. Downplayed in the animated show, where most of them are more hilariously incompetent than outright abusive.
  • Social Services Does Not Exist: They certainly don't exist in the book series considering all the cruel, messed up, and outright criminal acts the teachers can get away with while mistreating their students.
  • Took a Level in Kindness: In the animated series. Make no mistake, they're still jerks who enjoy making kids suffer, but they're much more likable compared to their book counterparts thanks to them having fleshed out personalities and quirks along with being hilariously incompetent at their jobs.

    Ms. Tara Ribble

From Left to Right (Movie, Book/Wedgie Woman, Cartoon)
Click here to see her as the "Homework Hydra"
Click here to see her as the "Queen of the Zombees"
Voiced by: Dee Dee Rescher (movie), Laraine Newman (animated series)

George and Harold's homeroom teacher as well as the Wicked Wedgie Woman in Book 5. She, like many of the faculty members, enjoys being cruel to her students by having them complete long and difficult assignments that meet her standards.


  • A Day in the Limelight: Gets one in book 5 where she gets some focus on her personality and some action as a Monster of the Week.
  • Bee Afraid: In the animated series; her stint as a Monster of the Week involves turning into the queen of a horde of "zom-bees" consisting of mutated students and staff.
  • Beehive Hairdo: Carries this in the books, the movie, and the animated series. It turns into an actual beehive when she becomes the Zom-bee Queen.
  • Bizarre Taste in Food: She loves chunky tofu ice cream.
  • Borrowed Catchphrase: She called Mr. Krupp "bub" in one book.
  • Breaking the Fourth Wall: She does this in book 5. While reprimanding the boys for their comic, she references the narrator's commentary on how "imagination isn't allowed at Jerome Horwitz" from a previous chapter.
  • Butt-Monkey: She's this in George & Harold's comic book. She also falls victim to George & Harold's pranks (once in the movie) and even loses her hair twice.
  • Child Hater: Like every other teacher at Jerome Horwitz, she hates her students. Book 5 shows that she has a framed certificate in her house for winning the "Meanest Teacher of the Year Award".
  • Demoted to Extra: In the movie.
  • Disproportionate Retribution: After George and Harold unintentionally trick Mr. Krupp into marrying her in Book 5, she deliberately changes all their grades to Fs and Gs so they'll flunk fourth grade.
  • Distaff Counterpart: Is practically a female Mr. Krupp in design. It's lampshaded in book 5 when she makes fun of Krupp's stubby, pig-like nose (which she also has). Also, Mr. Krupp became the superhero Captain Underpants as a result of hypnosis Gone Horribly Right, while Ms. Ribble became the supervillainess Wedgie Woman due to hypnosis Gone Horribly Wrong.
  • F--: As explained above, in Book 5 she changes the boys’ grades to Fs and Gs after the marriage proposal prank so they'll flunk fourth grade. Then in episode 3 of the animated series, she gives the boys' essays the grade of H for "Horrendous".
  • Fat Bitch: She is as chubby as Mr. Krupp and she is very unfair to the students.
  • Flat Character: Disregarding her bitterness and cruelty towards kids, she doesn't have a fleshed-out personality or even any interesting quirks that make her more dimensional compared to her colleagues.
  • Friend to All Children: Post-Heel–Face Turn, she turns into a kind teacher who bakes chocolate chip cookies for her students every day. This lasts until Book 12 at least, when she goes back to her old ways.
  • Heel–Face Brainwashing: After the events of the fifth book, Harold and George brainwash Ms. Ribble into becoming the sweetest teacher at Jerome Horwitz Elementary, but she seems to go back to her old ways in the final book.
  • Hypno Fool: George and Harold try to hypnotize her into changing their grades back, and to not do anything crazy like turn into Wedgie Woman. Given that the Hypno-Ring was revealed to have opposite effects on women immediately beforehand, this goes about as well as you'd expect.
  • Hypocritical Humor: She calls Mr. Krupp's nose stupid even though her nose looks exactly like his.
  • Iconic Item: In all three incarnations, she's always shown with her pointy glasses, pearl necklace, and earrings.
  • Jerkass: Her prime personality, at least until her Heel–Face Brainwashing. But during the final book, she turns evil again for no given reason.
  • Kick the Dog: At her retirement party, she tears up several of the cards her students gave her because they drew polka dots on their butterflies. One boy who drew a smiling sun on his card is forced to stand in the corner.
  • Meaningful Name: Her name is a pun on the word "miserable." Given her personality in earlier books, she lives up to that word.
  • Never My Fault: While it was immature & wrong for George & Harold to trick her & Mr. Krupp into (almost) getting married, Ms. Ribble decides to put the whole blame on the boys for the wedding & changes their grades to failing grades to get them to flunk the fourth grade. She ignores the fact that she and Mr. Krupp had a whole week to simply tell the other staff members that neither of them wanted to get married to each other and that they were a victim of a prank. It doesn't help that the prank George and Harold did was intended to be a small prank that people will just laugh at and then move on.
  • Older Than They Look: Downplayed in the books and animated series. She looks like she's in her forties but she's old enough to retire.
  • Perpetual Frowner: Is always shown with a disapproving frown.
  • Power Makes Your Hair Grow: And prehensile when she turns into Wedgie Woman.
  • Punny Name: Ms. Ribble is a pun on "Miserable" while her full name Tara Ribble is a pun on "Terrible".
  • Recurring Boss: She's been the Monster of the Week more times out of all the faculty members. She was the main head for the "Homework Hydra", the Queen of the Zombees, and the Wicked Wedgie Woman if you count the book series.
  • Sadist Teacher: Before the events of book 5. Her animated counterpart also counts but her sadism is not as high as her book self.
    • Subverted in the movie. She's just apathetic and uncaring about the information she's teaching to her students.
  • Superpowered Evil Side: Make that Superpowered Eviler Side, when she gains the Wedgie Woman persona in book 5. Granted, she didn't initially have superpowers, but after getting a load of Super-Power Juice dumped in her hair...
  • Took a Level in Jerkass: In the final book, she goes back to being just as evil as the other teachers for some unexplained reason.
  • Took a Level in Kindness: Thanks to some reverse hypnotism, George and Harold alter her into a kind teacher who loves to have fun with her students.
  • Trademark Favorite Food: Her favorite flavor of ice cream is chunky tofu, which she forces the students to eat at her retirement party.
  • Womanchild: After her Heel–Face Turn, she has tendencies of this. An example is in book 6 when she joins the kids in pulling "squishies" prank on the other staff members.
    • Before she was brainwashed, she even joins the teachers in bullying children, especially George and Harold.
  • Would Hurt a Child: She was all too willing to harm George & Harold in book 5 when they unintentionally tricked her and Mr. Krupp into marrying each other.
    Ms. Ribble: I'M GONNA GRIND THOSE KIDS INTO HEAD CHEESE!!!

    Mr. Kenny B. Meaner

Click here to see him as "Flabby Flabulous"
Click here to see him as "Sergeant Boxers"
Click here to see him as "Blah Borelock"
Voiced by: David Koechner

The main gym teacher of Jerome Horwitz. Despite being as bright as a sack of bricks, he torments his students by making gym class a living hell for them.


  • A Day in the Limelight: He's the villain of the 12th book.
  • Asshole Victim: In the comics that George and Harold write.
  • Ass Kicks You: As Flabby Flabulous, he uses his butt to destroy any obstacles and kick hero butt.
  • Big Bad: Of Book 12.
  • Big Fun: His alter-ego of Sergeant Boxers. He goes from a sadistic gym teacher to a lovable and energetic Fratbro.
  • Blob Monster: As Sir Stinks-a-Lot, he turns into a giant blob of energy.
  • Book Dumb: Academics aren't his forte. His hero alter-ego Sergeant Boxers is even worse since he admits that he can't read and can't even count to 5 correctly.
  • The Bore: He has a bad habit of boring people to sleep with his overtly-long stories. This becomes weaponized when he transforms into the Blah Borelock.
  • The Bus Came Back: His alter ego Sergeant Boxers makes an appearance during the season 3 finale, after not making an appearance since the season 2 premiere.
  • Butt-Monkey: He's always this in the comics that George and Harold write, where he's the "gym teacher" who's the victim of the latest villain, only for the principal to not care.
  • Carpet of Virility: Book 11 displays him with a hairy chest.
  • Chekhov's Gunman: Mr. Meaner has been around from the very beginning of the series, but never really did anything significant aside from getting eaten by a toilet in the second book. That is until Book 12 came along.
  • Embarrassing First Name: According to the creators, his name is Kenny.
  • Evil Sorcerer: His archetype as Blah Borelock.
  • Fat Bastard: Overweight? Check. Sadist Teacher? Check. He's second only to Mr. Krupp in both departments.
  • Final Boss: He is the final enemy faced in the book series, as Sir Stinks-A-Lot.
  • Fratbro: As Sergeant Boxers.
  • Gym Class Hell: His gym class is very difficult, though George says that gym was the easiest class in Season 2.
  • Half-Identical Twins: Season 3 reveals that Meaner has a twin sister named Misty Meaner who is just like him in appearance and voice. The key difference is that Misty has a ponytail.
  • Hero of Another Story: In season 3, he's revealed to have returned a star-like alien to its home planet and fought to protect its race in an intergalactic war. As a reward for his service, the star people turned him into a star-like them and granted him immortality.
  • Hidden Depths In season 1, he admits that he was interested in becoming a surgeon but couldn't apply since he never finished high school and used to be a non-U.S. resident.
    • In season 3, he claims to be colorblind.
    • When he finds one of George and Harold's comics, he's briefly seen chuckling a little as he reads it before realizing it's about him and getting angry.
  • Hypocrite: He is overweight yet he picks on students for not performing well nor being fit in his classes.
  • Jerk Jock: He's a gym teacher who mistreats the kids.
  • Karma Houdini: In Book 12, he faces no consequences for trying to brainwash all the children in Piqua into being obedient slaves for profit or flat out killing Captain Underpants.
    • In the animated cartoon, despite capturing the Chupabacra's lover, Meaner gets away scot-free after she finds a new partner in Poopacabra.
  • Kicking My Own Butt: He ends up hurting himself with a computer monitor when trying, and failing, to turn it on.
  • Lovable Jock: He's more friendly as Sergeant Boxers.
  • My Grandma Can Do Better Than You: Heck, his comic depiction pretty much quotes the trope name verbatim at one point.
  • My Friends... and Zoidberg: In Book 12. The citizens of the public are cheerful and full of relief when Old George, Old Harold and their hamster-pterodactyl pets emerge from the blobby remains of Sir Stinks-A-Lot completely unharmed. But when Meaner pops out, the cheering immediately stops.
  • One-Winged Angel: Near the end of Book 12, he turns into the titular Sir Stinks-A-Lot after eating an egg-salad and dill-pickle relish sandwich that supercharges the minerals that boosted his intelligence in the first place.
  • Punch-Clock Villain: Heavily suggested in the animated series. He gets along pretty well with the boys outside of gym class. And on an overnight camping trip with the kids in Season 3, he tries (and fails) to wow them with his overtly long stories.
  • Punny Name: "Misdemeanour". And his full name is a pun of "can he be meaner".
    • "Blah Borelock" is a pun combo of the words "blabber", "boring" and "warlock".
  • Recurring Boss: Next to Ms. Ribble, Meaner has been the Monster of the Week more times out of the other faculty members.
  • Sadist Teacher: Picks on the out-of-shape kids.
  • Ship Tease: With Harold’s Mom of all people in the Halloween Special.
  • Spanner in the Works: In the Season 2 premiere, he's the only teacher who isn't trapped in the school lounge by the Teachertrons. This would result in their downfall as the boys turn him into a backup superhero to save the day.
  • Starter Villain: In the cartoon, he's the first villain the boys face under the alter ego Flabby Flabulous, which is ironic considering that he's the Final Boss in the book series.
  • Super-Intelligence: In Book 12, he becomes a supergenius after eating a chunk of what used to be Smart Earth.
  • Superpowers for a Day: With Captain Underpants unavailable to help them in the Season 2 premiere, George and Harold hypnotize Meaner into becoming the Jockbro Hero: Sergeant Boxers, a meatheaded athlete hero who can take on an army of Teachertrons without breaking a sweat.
  • Suspiciously Similar Substitute: His heroic alter ego is pretty much Captain Underpants only significantly stronger and with a sports theme.
  • Taken for Granite: As the Blah Borelock, his ramblings can create gray smoke that can turn anyone into stone.
  • Took a Level in Kindness: In Season 3. Excluding the whole “Blah Borelock” incident, he is not as antagonistic towards the kids as he was in the previous two seasons.
  • Verbal Tic: Has one in the animated series; he tends to go "Yea-Yea-Yea-Yea" in a stutter-like fashion when speaking. Season 3 reveals that this is a Shared Family Quirk, as not only does his twin sister Misty have it, but so did their father.
  • Why Did It Have to Be Snakes?: In the animated series, it’s revealed that he's terrified of Chupacabra. It's explained in season 2 that Meaner ended up capturing Chupacabra's lover while on vacation and had him taken to the authorities. She's been after his tail for vengeance ever since.

"Did you call me?"
Click here to see her as "Clogneta"
Voiced by: Patty Mattson

The school secretary. She often gives Mr. Krupp a hard time with just about anything.


  • '20s Bob Haircut: Her hairstyle comes off as this.
  • Ambiguous Situation: The exact reason as to why she's at the summer camp in season 3 despite Krupp never asking her to come is never explained.
  • Beleaguered Assistant: She borders on this in the cartoon whenever she has to put up with Mr. Krupp's and later Melvinborg's antics.
  • Big Ol' Unibrow: She has one in the cartoon.
  • The Bore: George considers her to be a textbook definition of boring, much to her sorrow.
  • Catchphrase: "Did you call me?", as a part of a Running Gag in the first and second seasons.
  • Creepy Monotone: Her tone of voice in the animated series.
  • Deadpan Snarker: In the books, she loves to snark at Mr. Krupp. She also has a few moments in the animated series, with a lot more emphasis on the "deadpan" part.
  • Evil Is Hammy: As Clogneta, she becomes overly dramatic and super-expressive as she gloats about her powers and desire for world domination.
  • Expy: Her villainous alter ego is based off of Magneto.
  • Fantastically Indifferent: Regardless of what kind of crazy things she's experiencing in the animated series, she always has her Creepy Monotone style of voice.
  • Hidden Depths: In the Halloween special, she's revealed to enjoy beekeeping.
  • I Just Want to Have Friends: It's strongly suggested that she wants this when you consider how she always reaches out to Krupp in the animated series. Examples include how she admits to making guacamole for Krupp and how she came to the summer camp to be with him despite never being asked to do so on both occasions.
  • Incoming Ham: Her first words as Clogneta, showing how different she is from Ms. Anthrope:
    Clogneta: I am the baroness of blockage! The sovereign of sewage! I command the power of obstruction! I am… CLOGNETA!
    Choir: CLOGNETA!
  • Jerkass: Played straight in the books; downplayed in the movie and series, where she's more apathetic than anything.
  • Kind Hearted Cat Lover: In the cartoon, Ms. Anthrope is shown to own several cats and has her moments of kindness.
  • Monster of the Week: In Season 2, the boys accidentally turn her into Clogneta, a powerful, ego-maniacal villain who can control all forms of clogs and sewage.
  • Opaque Lenses: We can't see her pupils thanks to them.
  • Pet the Dog: It was rather generous of her to take care of the preparations for Mr. Krupp and Ms. Ribble's "wedding" in Book 5, even if it backfired spectacularly.
    • In the animated show, she wanted to bring balloons and colors to make the school dance more enjoyable.
    Ms. Anthrope: It's a dance. We can have fun things.
    • After Mr. Krupp gets demoted to Vice-Principal by Melvinborg, she offers him some of her jellybeans as an act of sympathy.
  • Punny Name: Ms. Anthrope is a pun on "misanthrope", while her full name, Edith Anthrope, is a pun on "eat it and throw up".
  • Race Lift: In the movie and the animated series, she's African American.
  • Rose-Haired Sweetie: Averted in the books, where she has deep magenta hair and is a straight-up jerkass.
  • Running Gag: In the animated series, she has a habit of walking into a room where Krupp is having a moment asking if he called her. Following Krupp being frustrated by her appearance and a Beat, she says something off-topic or random.
  • Sassy Secretary: Mostly in the books. She does not put up with Mr. Krupp’s crap at all.
    Mr. Krupp: Where's my coffee, Edith?
    Ms. Anthrope: Get it yourself, tubby!
    Mr. Krupp: I don't need your lip today, woman! I just want my coffee and I want it NOW!
    Ms. Anthrope: Well, get me a cup, too, while you're at it.
  • Self-Deprecation: While dressed up as Meaner in the Halloween Special, she admits that she "likes being someone else". This implies that she has some self-esteem issues she needs to work out.
  • "Shaggy Dog" Story: In the movie, George tricks Ms. Anthrope by pretending to be a game show host and asking her to hold onto the phone if she would like to win $1 billion, leading her to stay on the phone throughout the entire movie. In a mid-credits scene, she's still on hold and it's only by George calling her again does she hang up on accident. This leads to her having a raging meltdown for losing her chance at the prize money. And then the boys base their next comic on Anthrope and her meltdown.
  • Ship Tease: With Captain Underpants. After he saves her in book 6, she kisses him several times, hugs him, and wishes him good luck.
    Ms. Anthrope: (coyly) Now go get him, tiger.
  • Shipper on Deck: In book 5, she seems way too eager to plan Mr. Krupp and Ms. Ribble's wedding.
  • Would Hurt a Child: In the books. After getting yelled at by Melvin, who was actually Mr. Krupp after they underwent a "Freaky Friday" Flip, she gives him a wedgie by hanging his underwear on a wall coat rack. It should also be noted that Ms. Anthrope didn't even know about the switch and thought he was an actual child who warranted her anger.

  • Monster of the Week: In Season 2, the boys willingly transform him into Cloggernaut, an incredibly strong, clog-themed villain, to prove a point to Erica.

  • Pet the Dog: In the animated series, he suggested bringing in a mechanical bull so the school dance can be more fun.

Click here to see him as "Avocadwoe"
Voiced by: Mel Rodriguez (movie), Stephen Root (animated series)

The main science teacher of the school. A timid and fragile man who often has the worst of luck.


  • Adults Are Useless: One of the biggest examples among the cast. He pretty much lets the children do whatever they want while he tries a variety of ways to stay relaxed.

  • And Then John Was a Zombie: He turns into an avocado tree at the end of his episode.
  • Berserk Button: He loses his composure when it comes to loud noises.
  • Beware the Silly Ones: Despite his dorkiness and stupidity, he ends up turning into a giant, rampaging avocado pit monster in the series.
  • Butt-Monkey: In all three incarnations, he suffers some form of misfortune.
    • In the books, the chaotic events from books 1-3 are too much for Mr. Fyde's mental health that he decides to quit and goes to live at the "Piqua Valley Home for the Reality Challenged".
    • In the movie, Mr. Krupp fires him after he requests to take a Saturday off to spend time with his family.

  • Monster of the Week: Using Melvin's machine, the boys accidentally turn him into Avocadwoe, a giant and hyper-aggressive avocado monster who intends to destroy all noises no matter the cost.
  • Nervous Wreck: The whole reason he quit his job in the first place is that he had a nervous breakdown after several instances of witnessing the story's events. The series also reveals that, despite his 6 months at the home for the reality-challenged, he still hadn't gotten any better. If anything, he only got worse.
  • Opaque Nerd Glasses: He has these to showcase his fragility.
  • Punny Name: Mr. Fyde is a pun for "mystified" while his full name, Morty Fyde, is a pun for "mortified".

"Turn down that racket!"
Click here to see her as "DJ Drowsy Drawers"
Voiced by: Tress MacNeille

The school's elderly music teacher who is in serious need of a belt.


  • Fun-Hating Villain: One of the straightest examples of this trope. It's thanks to her that the school dances have always been so boring and dreary.
  • Grumpy Old Woman: She's one of the oldest members of the faculty and is always in a grouchy mood.
  • In-Series Nickname: Mr. Krupp always referred to her as "Droopy Drawers."
  • Just Eat Gilligan: Played with. While getting a belt certainly wouldn't solve all the series' problems, it would still stop her constant droopy drawers issue. But doing so would get rid of one of the show's running gags.
  • Killed Off for Real: The Mega Blissmas special showed her as a ghost, with no explanation on what happened and how she died.
  • Monster of the Week: After crashing into a van carrying toxic waste along with an amped-up ice cream truck, Ms. Hurd transforms into DJ Drowsy Drawers, a cyborg capable of putting anyone to sleep with her hypnotic sound blasts.
  • Musical Assassin: As DJ Drowsy Drawers, she uses her sound system to make anyone around her fall asleep. She can even use vintage records as firing projectiles.
  • Noodle Incident: How and why she developed a fear of werewolves vomiting is never explained.
  • Perpetual Frowner: It's rare to see her in a good mood.
  • Punny Name: Her name is a pun for the word "misheard".
  • Running Gag: Her pants keep falling which exposes her bloomers. Seriously, why doesn't she have a belt?
  • Why Did It Have to Be Snakes?: Her biggest fear is werewolves that are vomiting. It's so bad that she once stayed home for days and survived by eating her own eyelashes and toenail clippings.

Click here to see her as the "T.P. Mummy"
Voiced by: Maggie Wheeler

The French teacher who loves everything related to France and French culture.


  • Demoted to Extra: She rarely appears after her debut episode.
  • Drunk on the Dark Side: After turning into the T.P. Mummy, she planned to control all of the toilet paper in the world and would only give it away if everyone made her their queen.
  • Graceful Ladies Like Purple: Her outfit consists of different shades of purple and she has the femininity of a Frenchwoman.
  • Gratuitous French: Befitting her love of all things French, she likes to use as many French words in her dialogue.
  • Monster of the Week: Due to a major clogging incident with the schools' toilets, Ms. Yewh becomes the T.P. Mummy, an ill-tempered toilet paper mummy who intends to control all the toilet paper in the world.
  • Mummy: As the Monster of the Week, despite not actually being dead.
  • Oblivious to Love: She's completely unfazed and oblivious to Krupp's awkward flirting and romantic intentions.

  • Rescue Romance: After being "rescued" from her alter ego as the T.P. Mummy thanks to Mr. Ree, she develops a crush on him.
  • Satellite Love Interest: She doesn't have a solid character apart from being Krupp's and later Mr. Ree's love interest.
  • Suspiciously Similar Substitute: Of Edith the Lunch Lady from The Movie. Yewh is one of the nicer faculty members along with being one of the few people Krupp treats with actual respect and kindness because of his huge crush on her.

Click here to see him as "Colonel Urinal"
Voiced by: Clancy Brown

The school janitor (who totally doesn't have a secret past) that was introduced in the animated series.


  • Acrofatic: His body size is similar to his equally heavyset colleagues but he's capable of performing impressive athletic feats.
  • Almighty Janitor: A literal example. He's the prime custodian of Jerome Horwitz and is more cool and talented than he leads on.
  • Back-to-Back Badass: In "The Cunning Combat of the Covert Camoflush", he teams up with Erica Wang to stall the titular villain while the boys go to fetch Captain Underpants.
  • Baritone of Strength: He has a deep, masculine voice provided by Clancy Brown, and he's an Almighty Janitor who's capable of some impressive feats.
  • Badass in Distress: The Splotch uses his body and mind to advance its own plans.
  • Brainwashed and Crazy: By the Splotch in the latter's second episode.
  • Collector of the Strange: He enjoys collecting clothes and toys from the Lost and Found box. He even cites it as the primary perk of his job.
  • Come with Me If You Want to Live: Says this almost word for word to George and Harold after rescuing them from the T.P. Mummy.
  • The Comically Serious: One of the most serious characters on the show who has a whole career and identity dedicated to toilet humor.
  • Dark and Troubled Past: He was a part of a government waste disposal program that went horribly wrong, which he blames himself for.
  • Deadpan Snarker: He isn’t afraid to snark at Mr. Krupp now and again.
    Mr. Ree: (to Mr. Krupp about the new French teacher, Ms. Yewh) So, you got a crush on the "Ooh-La-La"?
    Mr. Krupp: What? That's ridiculous! (proceeds to swoon a little) It's not like I want to take long walks at the movies, trading… butterfly kisses… or-or anything!
    Mr. Ree: Whatever floats your boat, chief.
    Mr. Krupp: My boat floats fine!
    Mr. Ree: (smirking) …Liar.
    Mr. Krupp: WHAT?!
    Mr. Ree: Yeah, you heard me.
  • Did You Just Flip Off Cthulhu?: As shown in the example above, he stands out as the only faculty member who can actually mess with Krupp and get away with it.
  • Early-Bird Cameo: He briefly appears in episode 2 as a background character during the school dance.
  • Elaborate Underground Base: He has a secret base underneath the school that has technology from his old job at T.E.R.D.S.
  • Embarrassing First Name: In season 3, we find out that it's "Toilette", the French word for toilet.
    Mr. Ree: [My] parents were French-Canadian! …They loved bathrooms.
  • Expy: He ends up becoming the Eddie Brock to Splotch's Venom in the latter's second appearance.
  • Foolish Sibling, Responsible Sibling: He is the responsible, calm, and rule abiding sibling to Major Messy/Lavator Ree's foolish, hot-headed, and rule defying sibling.
  • Fun with Acronyms: His inventions and professions are named after bathroom themed acronyms.
  • Gadgeteer Genius: He's knowledgeable when it comes to advanced technology. It's because of this fact that the Splotch targets him as his next human host to use his brains for his world takeover plot.
  • Hidden Depths: He seems to be interested in kimonos.
  • Immigrant Patriotism: Subtly done. He's French-Canadian by birth, but worked his way up to become a high-ranking and trusted American official.
  • Ink-Suit Actor: He bears somewhat of a striking resemblance to his voice actor, Clancy Brown.
  • Perma-Stubble: Has a five o'clock shadow.
  • Punny Name: His name is a pun on the word "mystery". And his full name, Toilette Ree, is a pun on the word "toiletry".
  • Rescue Romance: After saving Ms. Yewh from her evil alter ego, she develops a romantic crush on Ree and the janitor appears to reciprocate her feelings.
  • Scare 'Em Straight: He does this to his brother to make him realize why it's important to have rules and order, by taking him on a joyride with a near-empty jetpack and letting them free fall.
  • Sibling Team: He has a brother named Lavator who used to work alongside him as a fellow researcher after the tragedy at T.E.R.D.S.
  • Superpowers for a Day: Averted. In the season 3 finale, the boys request him to become the Bathroom Hero: Colonel Urinal for a talent show and Ree was all too willing to accept. He doesn't get superpowers from the costume, but that doesn't stop him from kicking bad-guy butt when Melvin creates super villains to ruin the talent show.
  • Token Good Teammate: He's definitely nicer compared to his coworkers, and even helps/saves George and Harold in his episode debut.
  • Took a Level in Jerkass: Despite being of the few "good" adults in the show, he supported the cancellation of Halloween in the Halloween Special.
  • Trauma Button: Initially, he panics whenever he starts to think about his past job. He seems to overcome this later.

    Señor Jerry Citizen

Click here to see him as "Judge JORTS"

Voiced by: Jim Rash

The newly hired Spanish teacher. He's emotionally fragile and is in desperate need of a purpose in life.


  • Broken Bird: He's a sad, pathetic man who doesn't know what to do with his life.
  • Butt-Monkey: Life isn't willing to give the poor guy a break.
  • Catchphrase: He tends to whine out "Whyyyyyyyyyyyy?" a lot.
  • Clothes Make the Superman: His super abilities as Judge J.O.R.T.S. come directly from the alien robe.
  • Failure Hero: Let's just say that being a superhero isn't his calling.
  • Geek Physiques: He fits the trope since he's pretty much a grown-up geek.
  • Gratuitous Spanish: Subverted. Despite being a Spanish teacher, he knows little to nothing about teaching the actual language.
  • The Klutz: The guy can't walk two steps without having some type of accident.
  • Momma's Boy: When asked what would cheer him up, his first response was a cruise to Alaska alongside his mother.
  • Nice Guy: Despite his klutziness and incompetence, he's a genuinely good guy who wants to do right.

  • Pet the Dog: He stands out as one of the few if only, teacher/faculty member that enjoys comics and encourages the boys to make one.
  • Prone to Tears: It doesn't take much to make him cry.
  • Punny Name: His title and last name make out the term "senior citizen".
  • Superpowers for a Day: After finding the sentient robe, Jerry can live out his life as the Justice Hero: Judge J.O.R.T.S. Doesn't mean he's any good at it though.
  • Tender Tears: Being a sensitive guy, he cries quite easily. And considering all his terrible luck, it's hard not to feel sympathy for him.
  • What Happened to the Mouse?: We don't know what became of Jerry after the heroes save him from the alien robe.

    Dr. Mentor 
https://static.tvtropes.org/pmwiki/pub/images/dr_demented.PNG
Voiced by: Laraine Newman

The new science teacher introduced in Season 2.


  • Achievements in Ignorance: Somehow creates an interstellar vortex purely by accident.
  • Ambiguous Situation: At the climax of her episode debut, Dr. Mentor ends up in a Police Lineup alongside a group of sinister-looking scientists; this could suggest that she may have a criminal background.
  • Einstein Hair: It's part of her appearance as a scientist.
  • Informed Flaw: According to Ms. Ribble, Dr. Mentor goes to the bathroom a lot more than the average person.
  • Labcoat of Science and Medicine: Her main attire.
  • Lady Looks Like a Dude: It's easy to mistake her for a man at first glance.
  • Out of Focus: Has the least amount of screentime and characterization compared to her colleagues.
  • Punny Name: If you sound her name out just right, it sounds a lot like "the tormentor".
  • Put on a Bus: Heavily implied considering that she doesn't appear outside of season 2 and season 4 showcases a new science teacher named Miss Singlink.
  • Remember the New Guy?: Was created as a replacement for Mr. Fyde but was never given a proper introduction like the other new teachers/faculty members.
  • Stupid Scientist: Implied to be this. She looks like a scientist but her first scene shows that she doesn't seem to be very good at teaching science.

    Miss Chivess 
https://static.tvtropes.org/pmwiki/pub/images/81da769d_663a_44a5_b4a7_8999f6d2e1e0.jpg

The boys' 5th Grade teacher who nurtures their love of writing and appreciation of literature.


  • Ambiguously Brown: Her appearance in the books suggest that she's a woman of color.
  • Cool Teacher: The boys think of her as such for not only being okay with their comics but also introducing them to classic literature that they actually enjoy.
  • Meaningful Name: Her name is synonymous for "playful, naughty, impish etc". It would make sense that the one teacher in Jerome Horwitz would be able to obtain the relatability and respect of the Prankster Kings themselves. Not to mention that encouraging them to continue their comics despite the faculty's negative stance on the subject can be considered "mischievous" on it's own right.
  • Punny Name: Her name is a pun for the word "mischievous".
  • Reasonable Authority Figure: She does have her limits when it comes to George and Harold's shenanigans, but she doesn't go overboard with her manner of discipline like the rest of the faculty.
  • Small Role, Big Impact: She doesn't gain much focus due to the story focusing on the Dog Man series, but her role as a cool and thoughtful teacher helps the boys refurnish their comic book talents.
  • Token Good Teammate: She stands out as the first teacher from the book series who actually likes the boys' comics and encourages them to continue writing.

    Edith the Lunch Lady 
https://static.tvtropes.org/pmwiki/pub/images/3d22d800_14e6_4de1_a12c_efc79dd71c01.png
"Oh, Edith... get your head out of the clouds!"
Voiced by: Kristen Schaal

A sweet-hearted lunch lady who works at the school. She has a not-so-obvious crush on Mr. Krupp but she's too insecure to express how she feels about him.


  • Adaptational Heroism: She's possibly a member of the same species as the Alien Lunch Ladies from the third book, but she doesn't seem to be evil and is a total Nice Girl.
  • Alien Among Us: According to director David Soren, there was a scene in an early draft of the film revealing that she would've been the movie's equivalent to the Alien Lunch Ladies from the third book.
  • All Girls Want Bad Boys: She has a crush on Mr. Krupp, a mean, disagreeable, child-hating principal.
  • Ambiguously Human: While nothing about her appearance suggests she's not human, she is not affected in any way by handling the radioactive cafeteria food, while Professor Poopypants and Melvin have to wear hazmat suits just to be near the stuff. Also note that she never takes her dishwashing gloves off...
  • Big Beautiful Woman: Her body shape is similar to her overweight colleagues and is beautiful both inside and out.
  • Brooding Boy, Gentle Girl: The gentle girl to Krupp's brooding boy.
  • The Cameo: She makes a cameo as a Christmas caroler during the cartoon's Mega Blissmas Christmas Special.
  • Canon Foreigner: Only appears in The Movie, replacing the lunch ladies from the third book, who were Adapted Out.
  • Covert Pervert: When Mr. Krupp snaps his fingers at the end of the movie to summon a waiter so they can leave a restaurant being attacked by Talking Toilets, he turns into Captain Underpants... meaning he rips off all of his clothes. While Edith is shocked at first, her gaze soon turns appreciative.
  • Hiding Behind Your Bangs: One eye is covered by her hair, as Mr. Krupp (or rather Captain Underpants) points out and compliments her blue eye.
  • Iconic Item: She's always shown with her yellow, rubber gloves, even when she's not on the job and taking Mr. Krupp on a date.
  • Innocent Blue Eyes: She has ocean blue eyes and is a good-hearted woman.
  • Lethal Chef: Zig-zagged. She does seem fully capable of making something edible, as seen with her casseroles for Mr. Krupp, but her leftover cafeteria food is so toxic it breaks Poopypants' toxicity counter.
  • Nice Girl: Edith is shy and awkward, but she's a kind lady.
  • Non-Standard Character Design: In The Movie, she is the only character to sport coloured eyes instead of the usual Black Bead Eyes.
  • One-Steve Limit: Averted; Edith is also the first name of Ms. Anthrope, although the latter's first name isn't mentioned in The Movie.
  • Opposites Attract: She's the bashful, kind-hearted love interest of cruel Child Hater Mr. Krupp.
  • Shrinking Violet: Especially when she's near Mr. Krupp.
  • Significant Birth Date: According to the creators, it's February 14th. Valentine's Day.
  • Stealth Hi/Bye: She performs the "hi" on a few occasions, startling others.
  • Through His Stomach: Bless her heart, she tries. She gives Mr. Krupp a tuna casserole with his name spelled on it in jalapeño peppers. Unfortunately, he doesn't know how to properly show his mutual feelings for her.
  • Token Good Teammate: One of the only ones in the faculty who isn't mean towards any of the kids. That doesn't make her good at her job, though, as she keeps a vat of leftovers in the kitchen that can apparently be used as nuclear super fuel.
  • Unwitting Instigator of Doom: It's thanks to Edith accumulating so many radioactive leftovers that Professor Poopypants can use that as fuel for his revenge scheme to destroy all laughter. Subverted later on, as it's those very same leftovers that ultimately give Captain Underpants superpowers.
  • What Does She See in Him?: It's anyone's guess as to why Edith would have the hots for Krupp of all people.
