Charlotte is full of little funny moments in the first movie.
When Clarisse is trying to explain posture to Mia, behind her back Mia is making funny faces. Charlotte keeps laughing and tries to hide it whenever Clarisse looks at her.
When Clarisse explains to Mia that princesses never cross their legs in public, you can see Charlotte discreetly uncross her legs.
Her reaction to Mia's "I want to show you my baby." (Mia is talking about her car.)
A meta example, it is revealed in the directors comedy that the editor would often cut to Charlotte's reaction during the training scenes as an easy edit. The editor cut away to Charlotte so much that in the credits, she is listed as "Charlotte Kutaway"
Clarisse's exaggerated imitation of a teenager's walk is so much funnier just for having Julie Andrews do it.
In the first movie whenever Mia steps on the lawn at the embassy, a pre-recorded announcement says "Get off the grass!" - and then yells the same thing in several different languages.
Clarisse and Mia are sitting in a couple of chairs, practicing proper car etiquette, and Joe is sitting in the chair in front of them, pretending to drive. He checks his watch and realizes he has somewhere to be, then pantomimes stopping the car, putting it in park, and removing the keys from the ignition before he gets up to leave.
Heather Matarazzo's delivery of "Has your grandmother turned into the big bad wolf?!"
After Mia eats a huge scoop of Genovian palate cleanser and the prime minister and his wife follow suit, the baron tells his wife "They are acting like monkeys." Cue Mia, the prime minister, and his wife actually acting like monkeys.
Car t-bones San Francisco trolley. Nun (yes, a nun) whips out her cell phone, dials 911, gets put on hold, and lets out an exasperated, "Oh, for the love of God!" It must be seen to be believed.
Mia shows up to the grand ball in casual clothes from the rain. As a journalist from a teen magazine starts getting excited, Lily turns to Jeremiah (the two of them have cleaned up well) and says "Why didn't we dress like her? We look like idiots!"
A Royal Engagement
The art of the fan scene in the second movie. That is all.
And all set to Gilbert and Sullivan's Three Little Maids From School Are We.
Mia's reaction to finding out who Nicholas really is. No Armour-Piercing Slap, no Groin Attack, instead a well placed stomp to the foot. Later on Clarisse gives her opinion on Mia admitting that she flirted with him at her ball.
Clarisse: As your Queen I simply cannot condone it. As your grandmother I say- right on.
After she treads on Nicholas' foot, Mia turns away with a "hmph" that would put Miss Piggy to shame.
Nicholas' sarcastic reaction to Mia's indignity that he didn't tell her who he was when they danced.
Lady Elyssa, a minor character, politely commenting to Andrew that they should probably leave when Mia and Nicholas start trying to one-up each other on their dates' achievements at the garden party: "I think they're starting a my horse is bigger than your horse run?"
After a moment of Slap-Slap-Kiss in the palace gardens during an event, and Mia shoving him off, Nicholas just cheerfully points out that Mia enjoyed it and asks if she wants to do it again.
It takes Mia a second to respond.
Mia just fell in the fountain in the palace gardens and walks up to Clarisse soaking wet. Clarisse looks her up and down and simply says, "Do I want to know?"
The entire archery training montage set to "Fun in the Sun," by Steve Harwell.
Possibly the funniest part is when one of Mia's arrows whizzes past uncomfortably close to Nicholas, and he just glances up from the book he's reading and gives her a totally blasé smile and wave.
The hilariously uncomfortable kiss between Andrew and Mia. Which cuts away to a goat as though to emphasise how incredibly non-sexy the moment is.
Paolo trying to justify a hairstyling choice for Mia's wedding.
Mia: I look like a moose.
Paolo: ... Yes, but very cute moose! Make all the boy moose go "HWAAAAH!"
