- The book starts with Roald Dahl snarking at parents who are completely oblivious to any fault their child might have, complete with giving examples of what he would write in an evaluation were he allowed to use the level of snark required.
- Matilda tricking and humiliating her father.
- Doubly so in the glue-in-the-hat incident, with Matilda innocently saying to her father "What's the matter, Daddy? Has your head suddenly gotten bigger?"
- The parrot scene is hilarious.
- Matilda tricking and humiliating her father.
Zinnia: I think your head is swollen, Harry.Harry: The fibers are fused to the head!!Zinnia: "The fibers are fused"? What's THAT supposed to mean?!
- The incident when Matilda puts superglue on Harry's hat:
Harry: From now on, this family does exactly what I say WHEN EXACTLY WHEN I SAY IT!
- "I still don't understand how you glued your hat on, Harry. I mean, I know you say you didn't, but obviously, you did."
- Also, this bit after Zinnia manages to get the hat off:
- Also, the bit with peroxide in the hair tonic, leading to the page image.
- Then there's the fact that the parents are too stupid to put two and two together and deduce that Matilda may have played pranks on them.
- Mr. Wormwood was a jerk to Matilda the night before. His bathroom has a bottle of peroxide and the hair oil is purple and made with violets. He never once considers that someone may have put peroxide in the bottle or notice the color of the "oil" may be lighter.
- Mr. Wormwood has just showed his son how to "Super Super-Glue" a bumper to a car....then berates Matilda when she calls him out on his fraud. Rather than considering that "Matilda got back at me by putting glue in my hat", he and his wife come up with weirdness involving head-swelling or hair/hat-fiber-fusion.
- Many of the bits with the goofy FBI Agents.
- When Matilda comes home at night after the whole cake scene. The agents are in a car, watching a "Red Asphalt"-type video while eating.
- The Wormwoods (at least Zinnia) are stupid enough to fall for their "Speedboat Salesman" spiel.
- When Mr. Wormwood kicks one of them out (Paul Reubens), the agent goes, "Are you interested in time-share"?
- The cheesy "secret agent"-type music that plays when they're snooping in the Wormwood's garage.
- The agents arguing over who gets to use the camcorder during the Garage-snoop. In fact; The dynamic between the agents, period.
- The Trunchbull going on a bestial rampage while searching for Matilda and Miss Honey in her house.
- Just before her rampage, the Trunchbull sniffing at her favorite chocolate box lid Wolverine-style and then her sudden twitch realizing she's not alone in her house.
- In the movie Trunchbull's line about playing a game called "who was wearing a pretty red, hair ribbon yesterday, and isn't wearing one today?". The line delivery can crack one up, even though it's probably not meant to be so funny. here
- The defeat of the Trunchbull is a Funny Moment of Awesome.
- Matilda's dad is full of hilarious moments, which isn't surprising since it's Danny DeVito playing him.
- When Matilda first shows Miss Honey her powers, she makes a pitcher of water levitate. Miss Honey, deep in thought, pushes the pitcher back down without even noticing. Matilda then does it again and Miss Honey notices. The look of surprise on her face is adorably funny.
- And then, when the Trunchbull walks in, the pitcher is still levitating, so Miss Honey grabs the handle and has to pretend she's just casually holding a pitcher of water there.
- Matilda magically makes a glass of water containing a newt tip over onto the Trunchbull, and Trunchbull's desperate attempts to get the creature off of herself are hilarious.
- After everything, Matilda decided to lampshade said moment to Lavender and Matilda imitating her "dance" when she tried to shake the newt off her chest.
- There's a brief moment when Trunchbull tries to blame Matilda for making it happen (correctly, but no one knows about Matilda's power at this point), and Miss Honey asks how Matilda could possibly have made it happen from across the room. There's a short moment of mental standstill as Trunchbull realizes that there really isn't any way even she could blame this on Matilda.
- Many, if not all scenes involving Ms. Trunchbull when they aren't nightmarish.
- WHY ARE ALL THESE WOMEN MARRIED?!
- Your mommy...is a TWIT !!
- Am I wrong? I'm never wrong. In this classroom, in this school, I am GOD!
- For this newt, you PISS-WORM!!
- When Bruce Bogtrotter finishes eating the cake. It's funny because the score in that scene sounds like it belongs in an epic film. It's funny how it takes a scene where a boy is eating cake seriously.
- During the start of the climax, Trunchbull's busy berating the kids and the kids respond to one of her questions:Kids: Yes, Miss Trunchbull.Boy: ...sir.
- Even some of the things Mr. Wormwood says and how he says it....[Leaving the hospital with a newborn Matilda] "$5,000?! I'm not paying it! What are they gonna do, repossess the kid?!"[Selling a car to Ms. Trunchbull] "In a manner of speaking, yes. Uh, welcome to Wormwood Motors. Harry Wormwood, owner, founder, whatever!"[Michael chokes on a carrot Matilda just shoved in there] "Chew yer food! You're an animal!"
- When Ms. Honey visits Ms. Trunchbull's office. Trunchbull's antics before she steps in (target practice on kid photos with darts and javelin) is amusing. She's really enjoying herself.
- Mr. Wormwood's subtle reaction to Trunchbull's line about never being a child. It's like "Uh, Oooookaaayyy...."
- How hammy is the Trunchbull? When she's barking over the PA system, the speaker's mesh actually pulses in and out at though she was yelling just behind it.
- Matilda arguing with her parents about her age.Harry: Dearest pie, how old is Matilda?Zinnia: Four.Matilda: I'm six and a half, mommy.Zinnia: Five, then.
- Trunchbull is getting ready to leave her house in her car, but suddenly, a black cat approaches her, asking for her attention. As it turns out, Trunchbull is a superstitious person and is, therefore, terrified of black cats. The teacher is seen skipping backwards like a scared little girl and tries to scare it off by shaking her key-ring and barking like a dog, only to send it flying by kicking it away when it gets too close for comfort.
- From the musical, we have Agatha Trunchball's little... digression in the middle of 'The Smell of Rebellion'. Up till this point she's been singing about how she intends to weed out rebellious students from the school, and then suddenly she starts singing this. Full warning, It Makes Just As Much Sense In Context.Miss Trunchbull: Imagine a world with no children/ Close your eyes and just dream./ Imagine... come on, try it, the peace and the quiet/ a bubbling stream/ Now imagine a woods with a cottage,/ and inside that cottage we find/ a dwarf called Zeke, a carnival freak/ who can fold paper hats with his mind, and he says/ Don't let them steal your horses, no!/ Don't let them throw them away, no!/ If you find your way through, they'll be waiting for you/ singing... neigh! Neiiigh!
- Also from the musical, before Bruce starts eating the cake:Miss Honey: Headmistress, he'll be sick!Miss Trunchbull: He should have thought of that before he made a pact with Satan and decided to steal my cake!
- And then he does a giant burp and notes that it was "the biggest burp [he'd] ever done, the biggest burp [he'd] ever heard [and] the biggest burp [he'd] ever heard about."
- Matilda's birth scene.Mrs Wormwood: (goes out with a baby bump) "Well, doctor, what's wrong with me?"Doctor: "Mrs Wormwood, do you really have no idea?"Mrs Wormwood: "Gas?"Doctor: "Mrs Wormwood, I want you to think very carefully. What do you think might be the cause of this?" (points at Mrs Wormwoods's bump)Mrs Wormwood: "Am I...am I...look, am I fat?!"Doctor: "You're pregnant!"Mrs Wormwood: "What?"Doctor: "You're going to have a baby."Mrs Wormwood: "But I've got a baby! I don't want another one. Is there anything you can do?"Doctor: "You're nine months pregnant!"Mrs Wormwood: "Antibiotics?"[later, after Matilda is born]Doctor: "Mr Wormwood, are you smoking a cigarette?"Mr Wormwood: "What? Oh, of course. I'm sorry, doctor. What was I thinking? This calls for a proper smoke. (throws away cigarette and starts smoking a cigar, holds Matilda) Oh, my word, he's an ugly little thing."Doctor: "This is one of the most beautiful children I have ever seen."Mr Wormwood: (unwraps the baby's swaddling blanket) "Oh, my good Lord, where's his thingie?"Doctor: "His what?"Mr Wormwood: "His thingie. His whatchamacallit. His do-dah. What have you done with his thingie?"Doctor: "This child doesn't have a 'thingie'."Mr Wormwood: "What? A boy with no thingie? Look what you've done, you stupid woman. This boy's got no thingie."Doctor: "Mr Wormwood! This child is a girl."
- During the "Everything I Know, I Learnt from Telly" song, Mr Wormwood says "Who the dickens is Charles Dickens?"
- When Matilda dyes her dad's hair green, he tries to pretend it's "National Green Hair Day" to celebrate all the green things in the world. Only trouble is, the only green things he can think of are lettuce and snot.
- At a cast reunion, the now-grown child actors re-enacted famous scenes from the film, including the cake-eating and pigtail-toss scenes. It's as hysterical as it sounds.
