* Matilda tricking and humiliating her father, in both the book and film versions.
** Doubly so in the book's version of the glue-in-the-hat incident, with Matilda innocently saying to her father "What's the matter, Daddy? Has your head suddenly gotten bigger?"
** Hard not to love the movie version, too, is the incident when Matilda puts superglue on Harry's hat:
--> '''Zinnia:''' I think your head is swollen, Harry.
--> '''Harry:''' The fibers are fused to the head!!
--> '''Zinnia:''' "The fibers are fused"? [[GettingCrapPastTheRadar What's THAT supposed to mean?!]]
** "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:
--> '''Harry:''' From now on, this family does exactly what I say [[DepartmentOfRedundancyDepartment WHEN EXACTLY WHEN I SAY IT!]]
** Also; The bit with peroxide in the hair tonic....leading....to [[https://www.youtube.com/watch?v=KWRB3E3IPlg THIS!]]
** 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 [[ComicallySerious 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.
** "COME OUT AND FIGHT LIKE A MAN!"
** *jumps off stairs* "TALLY HO!!!"
*** Complete with a BombWhistle noise.
** "Some ''rats'' are gonna DIE today...!"
*** In a nutshell. The Trunchbull's often hilarious as she is terrifying.
* Just before her rampage, the Trunchbull sniffing at her favorite chocolate box lid {{Wolverine}}-style [[TheNoseKnows 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. [[http://www.youtube.com/watch?v=nSz19p1Z6i4 here]]
* The defeat of the Trunchbull is both a CrowningMomentOfFunny and CrowningMomentOfAwesome.
* 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.
* Many, if not all scenes involving [[LargeHam Mrs. 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 [[GettingCrapPastTheRadar PISS-WORM!!]]
* In the book, the parrot scene is hilarious.
* 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.
** That scene gets its own song in the musical. The music as he finishes the cake is the CrowningMoment of a [[CrowningMusicOfAwesome very good song.]]
* 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, ItMakesJustAsMuchSenseInContext.
--> 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'''!
* During the start of the climax, Trunchbull's busy berating the kids and the kids....
-->'''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! 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*'' "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...."

* At a cast reunion, the now-grown child actors [[http://www.buzzfeed.com/leonoraepstein/watch-matilda-cast-members-reenact-scenes-as-grown-ups re-enacted famous scenes from the film]], including the cake-eating and pigtail-toss scenes. It's as hysterical as it sounds.
