List of Fourth Wall Breaks in Captain Underpants

This is a list of fourth wall breaks in the Captain Underpants series. A fourth wall breakage is when characters mention them being in a book/movie/TV show. Examples of fourth wall breakages will be shown below.

The Adventures of Captain Underpants
While two robots are stealing a jewel, George exclaims "Up until now this story was almost believable!"

Captain Underpants and the Attack of the Talking Toilets
George says "They'll never let us get away with that in a children's book. We're skating on thin ice as it is!" when Harold suggests drawing a urinal robot in order to defeat the Turbo Toilet 2000.

Captain Underpants and the Invasion of the Incredibly Naughty Cafeteria Ladies from Outer Space (and the Subsequent Assault of the Equally Evil Lunchroom Zombie Nerds)
When the author mentions how a giant wave of green goop covered everything in school, one sentence reads "It traveled down the north, east, and west wings of this school, covering everything from the drinking fountains to the text on this page."

When Captain Underpants returns (shortly after ordering a cheeseburger at a nearby shoe store), George asks him where he was during Chapter 15 when they needed him (during the incredibly graphic violence chapter).

When Harold suggests his idea for conquering the evil zombie nerds and getting them to return to normal, George replies he was hoping for a more dramatic solution, but as they are running short of pages in the book, they could try it.

Captain Underpants and the Perilous Plot of Professor Poopypants
George tells Harold that he learned something today. The moral of the story ("I think this is the first time one of our stories ever had a moral," notes Harold) is that it's not nice to make fun of people.

Captain Underpants and the Wrath of the Wicked Wedgie Woman
After Ms. Ribble reads the comic book George and Harold make, George explains that all they did was use their imaginations, and Ms. Ribble snaps "You're not allowed to do that in this school! Didn't you read chapter 1?"

When the Extra Strength Super Power Juice pours into Wedgie Woman's hair, Harold grabs the juice carton and yells "NOOO! This is the juice we got from that spaceship back in our third book!"

After The Harold 2000 kicks the kickball into the air, it makes a hole at the top right corner of the page, which is also shown on page 102.

The police officers that are being hanged from two stop signs speak directly to the reader.

The text says "A huge cloud of mist filled the air, covering everything in sight, and making these two pages incredibly easy to draw."

Captain Underpants and the Big Bad Battle of the Bionic Booger Boy - Part 1: The Night of the Nasty Nostril Nuggets
George yells at the narrator to stop describing Melvin after he turned into the Bionic Booger Boy.

Harold notes that the endings to their adventures usually involve them saying "Oh no!" and "Here we go again!".

Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy - Part 2: The Revenge of the Ridiculous Robo-Boogers
Melvin says to Mr. Krupp that he "could solve this problem right away if [he] still had [his] Combine-O-Tron 2000, but it got smashed in the last book." when he is demanding him to try to switch their brains to the correct bodies.

Miss Singerbrains breaks the fourth wall by saying "Have you come to check out the book?"

George breaks the fourth wall saying Melvin's warning, "Back in chapter 12, starting with the first word in the third line of the second paragraph on page 77," and says "I'm not very good at remembering details."

Captain Underpants and the Preposterous Plight of the Purple Potty People
Harold says to Evil George and Evil Harold, "We read your comic book back in chapter 8!"

George yells at Harold saying, "Now I bet when you turn the page, something even worse is going to happen! You've gotta learn to keep your mouth shut at the end of these books!"

Captain Underpants and the Terrifying Re-Turn of Tippy Tinkletrousers
The Narrator says "But the police hadn't bothered to read the last book."

Captain Underpants and the Revolting Revenge of the Radioactive Robo-Boxers
Tiny Tippy and Slightly Younger Tiny Tippy both say "To go forward in time to chapter eight of our last epic novel?"

Captain Underpants and the Tyrannical Retaliation of the Turbo Toilet 2000
The Narrator says he has "quickly caught them both up on the events of the past three and a half chapters."

George, Harold, Yesterday George, and Yesterday Harold state "I guess there are a lot of loose ends in this story."

Captain Underpants and the Sensational Saga of Sir Stinks-A-Lot
When Harold says to order everyone to stop following orders, George says "We've already used that joke in this book."

When Old George asks the two boys how come he and Old Harold have no memory of doing anything like this when they were kids, Harold says "I don't know," and George says "Probably bad writing."

The Adventures of Super Diaper Baby
Deputy Dangerous says to the reader, "Remember that now," after the narrator introduces him and Danger Dog.

He later breaks the fourth wall again after saying Deputy Doo Doo.

The Adventures of Ook and Gluk: Kung-Fu Cavemen From the Future
Gluk says to the reader, "Remember that now," after the narrator introduces him and Ook.

Super Diaper Baby 2: The Invasion of the Potty Snatchers
Dilbert Dinkle says to the reader, "Remember that now," after the narrator introduces him and Petey The Cat.

Rip Van Tinkle breaks the fourth wall by saying they're not supposed to talk about poo.

Petey breaks the fourth wall by saying "We're not doing the rhyming thing anymore."

Captain Underpants: The First Epic Movie
George and Harold would talk to the audience in certain scenes.

The Epic Tales of Captain Underpants
In "The Frenzied Farts of Flabby Flabulous," Harold says "we're almost out of show."
