  • Any time George and Harold rearrange the letters of a sign so that it says something ridiculous.
    • Book 1:
      • A florist's shop that says "Pick Your Own Roses" becomes "Pick Our Noses".
      • The school sign saying "See Our Big Football Game Today" becomes "Boy Our Feet Smell Bad".
    • Book 2: A furniture store sign that says "Come In And See Our Pretty Armchairs" becomes "Come and See Our Hairy Armpits".
    • Book 3: The school menu advertising "New Tasty Cheese And Lentil Pot-Pies" becomes "Nasty Toilet Pee Pee Sandwiches".
    • Advertisement:
    • Book 4:
      • The school sign that says "Don't Underestimate Our Good Teachers" becomes "Our Teachers Don't Use Deodorant".
      • Another one has the same board saying "Pizza Palace Field Trips are Today" which becomes "Please Don't Fart in a Diaper".
    • Book 5:
      • A school bulletin board that says "People—Please Wear Your Socks On The Gym Floor" becomes "Please Go Pee-Pee On Your Socks For Warmth". The letters they didn't use even spell out "Y LOL" (Why LOL)!
      • Another board that says "Have A Blissfully Grand Retirement, Ms. Ribble" becomes "Ms. Ribble Really Needs A Breath Mint".
    • Book 6: A bulletin board saying "Please Wash Your Hands After Using The Toilet" becomes "Please Wash Your Hands In The Toilet". And Melvin falls for it!
    • Book 7:
      • A sign at a school entrance saying "National Fine Arts Academy" becomes "National Fart Academy".
      • Another sign saying "Check out our school's big internet website at" becomes "We shake our big butts when we swim in the toilet".
    • Advertisement:
    • Book 8: A sign saying "Push Button to Open Door" becomes "Push on Butt to Open Door", and a group of teachers fell for it straight.
    • Book 9: The display sign in front of Billy Bill's gas station was changed by little George from "Free Brake Inspection" to "Free Bra Inspection".
      • The context to this causes this to double as an Moment of Awesome. Billy Bill saw little Harold hiding behind the sign while trying to hide from Kipper and his thugs, and grabbed him and handed him over to those aforementioned bullies because Billy Bill thought little Harold was messing with the sign. George witnessed this and deliberately removed two letters from the sign to cause chaos, and the 'updated' sign prompted many old women to start attacking Billy Bill, believing him to be a misogynist.
    • Book 11: A sign at the hallway saying "Candy Bar Fund Raiser" becomes "Canned Barf Day".
    • Advertisement:
    • Book 12: A sign saying "Student and Teacher Art Fair Starts Wednesday." becomes "Teacher Farts Stain Underwear".
  • George and Harold's comics take a different approach to the aforementioned joke: many of them feature a Running Gag where a sign says one thing, but then it gets sliced, burned or smashed in half and says something else. Some examples:
    • "At Bob's Diner, you'll find that we pick the best ingredients. Your nose knows the difference!" becomes "At Bob's Diner, we pick your nose."
    • "Heyman's Gifts: Who makes the cutest gifts and the most delicious cheese? We do!" becomes "Hey, who cut the cheese?"
    • "My homemade buttermilk bread smells delicious! It's awfully good" becomes "My butt smells awful."
    • "Please drive very slowly over tracks: children at play" becomes "Please drive slowly over children."
    • "It's fun to shop, eat, and drink out of the mall. All of the stores have clean toilets and big sales!" gets turned into "It's fun to drink out of the toilet."
    • "I drink delicious warm apple cider from Pittsburgh's Fruit Juice Company!" becomes "I drink armpit juice."
    • "I went to Bob's Pools to buy my pool! Now I dive in my pool, swim under the waves and wear a big smile!" becomes "I went poo-poo in my underwear."

Book 1: The Adventures of Captain Underpants

  • The copyright page for the first book has a hidden gem: a small box that says "Sturgeon General's Warning: Some material in this book might be considered offensive by people who don't wear underwear." Capped off by a drawing of a fish with a cap and medal next to it!
  • Mr. Krupp recalling the pranks George and Harold have pulled throughout the years, one of them being the time they rigged the PA system to play "Weird Al" Yankovic songs for an entire school day.
  • Captain Underpants uses a pair of underwear to incapacitate Dr. Diaper, and we get this exchange:
    George: Where’d you get the extra pair of underwear?
    Captain Underpants: (wearing a barrel) What extra pair?
    George and Harold: (look, quite understandably, grossed out)
  • When the boys first hypnotize Mr. Krupp, they take the incriminating videotape (of them pranking the school football game) that Krupp was using to blackmail them. That's when Harold takes the opportunity to replace it with one of his little sister's old "Boomer the Purple Dragon Sing-A-Long" tapes. Then later, when Mr. Krupp is turned back to normal, he takes what he thinks is the security camera tape to the school's football team, the Knuckleheads. They wind up enjoying the video so much, they change their name to the Purple Dragon Sing-A-Long Friends!
    The name change didn’t go over too well with the fans, but hey, who's going to argue with a bunch of linebackers?

Book 2: Attack of the Talking Toilets

  • P.E.T.T: People for the Ethnical Treatment of Toilets. In fact, all of the disclaimers before the Flip-O-Rama in each book.
  • George and Harold propose making a robot urinal called the Urinator to fight the Turbo Toilet 2000, only to decide that "they would never be able to get away with that in a children's book". Made even funnier by the fact that this conversation was taken verbatim from one between Dav and his girlfriend over his original idea for the book.

Book 3: Invasion of the Incredibly Naughty Cafeteria Ladies from Outer Space (and the Subsequent Assault of the Equally Evil Lunchroom Zombie Nerds)

Book 4: Perilous Plot of Professor Poopypants

  • In George and Harold's comic-within-the-book, Professor Poopypants turns a group of gerbils evil by making them listen to Cher. Complete with disclaimer on the back cover:
    "Notice: All animal cruelty was simulated. No actual gerbils were forced to listen to Cher."
  • Almost all of the names from the Name Change-O-Chart 2000 are ridiculous, disgusting or unfortunate:
    Mr. Krupp: Oh, no! My new name is "Lumpy Pottybiscuits!"
  • George (Fluffy) and Harold (Cheeseball), while stuck in tar, pick a real bad time to use Buffy Speak.

Book 5: Wrath of the Wicked Wedgie Woman

  • "B-b-b-bubba-bobba-hob-hobba-hobba-wah-wah." The only thing Mr. Krupp is able to say when he learns he's getting married. And the school week before the wedding certainly wasn't helping.
    • Then, when it's about to happen, Ms. Ribble suddenly opts out because of how silly his nose looks. The accompanying illustration is a close-up on their faces to show that their noses look identical.
    • Mr. Krupp's Villainous BSoD lasts for an entire week. And note he's wearing a different tie for each day, implying he has just enough presence of mind left to get dressed in the morning.
  • The rabbi who comes to marry Mr. Krupp and Ms. Ribble in Wedgie Woman telling George and Harold that he doesn't want any tricks today. Harold's response? "Silly rabbi! Tricks are for kids!"
  • In the office, Ms. Anthrope has George and Harold distribute copies of the Friday Memo. But she leaves her computer on, allowing the boys to type up their own version. A hilarious week ensues:
    • No one showed up for school on Monday, much to the confusion of the faculty.
    • On Tuesday, all of the students were in their pajamas and picking their noses for the entire day.
    • The girls who wanted to join the cheerleading squad showed up on Wednesday with moustaches drawn on their faces and rotten egg salad sandwiches taped to their heads.
    • Thursday was hands down the most chaotic day of that week. A food fight broke out in the cafeteria at lunch, and the school football team trashed the teacher's lounge by using it for football practice.
    • Yearbook photos were taken on Friday with odd results. The students took their pictures in bumblebee costumes and made funny faces to try and win a pizza party for their class.
  • Another moment from the fifth book is how George and Harold defeat Wedgie Woman. By disguising several cans of hair remover as spray starch. The funniest part is that not only does Wedgie Woman lose her hair, but so does everyone else! Well, except for Captain Underpants, who was already bald to begin with.
    Harold: Aaugh! My mom's gonna lay hard-boiled eggs when she sees me!
    George: Relax. Our hair will grow back!
    Harold: That's easy for you to say. Your hair was only half an inch long!

Book 6: Big, Bad Battle of the Bionic Booger Boy, Part 1: The Night of the Nasty Nostril Nuggets

  • The introduction of the Bionic Booger Boy is Nausea Fuel incarnate, with increasingly graphic descriptions of just how Squicky the whole ordeal really is — to the point that George yells at the narrator to knock it off.
    George: ALRIGHT, ALREADY! Enough with the descriptions—you're making us all sick!
    Ms. Ribble: Thank you, George.
  • When Melvin (as the Bionic Booger Boy) sneezes, he ends up splattering the chalkboard with mucus. Ms. Ribble advises him to cover his mouth... which ends up making things ten times worse as it turns him into a snot-based Action Bomb.
  • At one point Mr. Krupp shows up in Ms. Ribble's class and demands to know why everyone is wearing raincoats and umbrellas. Then Melvin sneezes, and the next page has Krupp returning to the classroom with a raincoat, an umbrella, and a fresh set of clothes.

Book 7: Big, Bad Battle of the Bionic Booger Boy, Part 2: The Revenge of the Ridiculous Robo-Boogers

Book 8: Preposterous Plight of the Purple Potty People

  • Chapter 2 opens with:
    It's been said that adults spend the first two years of their children's lives trying to make them walk and talk... and the next sixteen years trying to get them to sit down and shut up.
  • How the villains get defeated. Captain Blunderpants gets beaten up by George and Harold's grandparents, while Harold uses reverse psychology to make Evil George and Harold shrink themselves.

Book 9: Terrifying Return of Tippy Tinkletrousers

  • An illustration of a news article detailing Mr. Krupp, George, and Harold's arrest and sentencing (in the original timeline where Tippy Tinkletrousers didn't show up in his time machine) mentions this, in a completely Non Sequitur fashion and in absolutely tiny print:
    Dr. Kent C. Toogood, president of the Doctors United to Banish Tiny Words in the Story (D.U.M.B.T.W.I.T.S.) warned that illustrations containing small words can cause eye strain, which could lead to headaches, nausea, and ridiculous acronyms.

Book 11: Tyrannical Retaliation of the Turbo Toilet 2000

Book 12: Sensational Saga of Sir Stinks-A-Lot

  • From the intro comic:
    One day George and Harold had a really BIG problem. So they stole [which is crossed out] borrowed a time machine.


  • This exchange in Super Diaper Baby after Deputy Dangerous is turned into Deputy Doo-Doo:
    Deputy Doo-Doo: Man, this hill is steep! I'm so tired!
    Danger Dog: Are you pooped?
    Deputy Doo-Doo: Why, yes, I'm... hey! Shut up!
    Danger Dog: Aw, don't be a party pooper!
    Deputy Doo-Doo: I said SHUT UP!
    Danger Dog: When we get home, will you read me Winnie-the-Pooh?
    Deputy Doo-Doo: (while Danger Dog is laughing) I'LL KEEEEEL YOU!
    • Earlier, when Deputy Dangerous finds out he's turned into poop, he looks in the mirror. He yells, "What the...I'm a piece of poo!" but his reflection yells, "What the...he's a piece of poo!"


  • Some of the "Fun Facts" at the end of the Full Color versions of the books are hilarious. For example:
    "You might notice a theme in George and Harold's comic books: The gym teacher always gets attacked by the villains, but nobody seems to care. This theme occurs again and again because many* of Dav Pilkey's former gym teachers were REALLY, REALLY MEAN to him. So let this be a lesson to gym teachers all over the world: Be nice to your students, or some day they might grow up and get revenge by making fun of you in their epic novels!" (*Note: Dav's lawyer told him to use the word "many".)
  • Mr. Krupp has had enough of the Angels' shenanigans.
