While everyone's arguing, the Judge says this about Nikos:
Judge: But if he turns out straight, I'm free at eight on Saturday!
Everyone on stage were second-guessing Nikos and whether or not he's really gay ...until Carlos showed up.
Nikos: I'm straight!
Carlos: You were not yesterday.
Several parts of "Ireland" and its reprise:
Orfeh's delivery of "Isn't that relaxing? It's called CELTIC MOODS!!!!!" Elle's expression is priceless.
In the original version's lyrics, Paulette claiming that Elle looks like a poster for Ireland...only to realize that she looks more like the poster for Sweden. She disregards it, deciding that she'll never see either place.
During the court case, Elle states that she would like to go to the bathroom, meaning the actual bathroom that Brooke's step-daughter was apparently having a shower in. The judge assumes she means that she needs to use the toilet. When Elle tries to clarify...
Elle: Your Honor! I would like to go to the bathroom. Judge: ...shouldn't you have gone before the murder trial? Elle: Oh no, I mean I would like us all to go to the bathroom, together. Warner: Why do girls always DO that!?
And then, when the entire court room goes to the bathroom, the Judge has to admonish Elle's parents and the Greek Chorus not to smudge the chalk outline. (The Chorus immediately engages in hopscotch.) The Judge herself ends up perched on the (closed) toilet, looking highly annoyed by how this day is going.
The court stenographer has only two lines in the entire musical, but they are gold:
Elle: Will the court stenographer please read that back? Stenographer:[Imitating the Chorus just moments before] "Omigod we rock! It's the scene of the cri-" Elle: Oh no, before that.
Better yet, the stenographer is recording the proceedings on a roll of toilet paper.
From "Chip On My Shoulder"
Emmett: What kind of rich romantic planet are you from?
Callahan: Miss Woods, excellent work today. I assume you're applying for my internship. Do you have a resume?
Elle: I am one step ahead of you. Here you go, and thanks in advance for your consideration.
Callahan:(beat) Dear God, it's scented.
The party scene with Elle in the Playboy Bunny outfit. Now, anyone who's seen the movie will be thinking, Okay, yeah, that was cute, but why is this a crowning moment of funny? Because of a slight change that the script writers included that was absolutely brilliant. After Vivienne tells her to go home and change out of her "skank costume," Elle immediately says that she is not, in fact, dressed as a Playboy Bunny, but instead as Gloria Steinem during her time working as a Bunny to do research for her feminist article "I Was a Playboy Bunny." She then loudly asks if Vivienne's calling Gloria Steinem a skank — cue slightly tipsy Straw Feminist Enid coming in and yelling "Who's calling Gloria Steinem a skank?" before chasing Vivienne off-stage looking ready to tear her hair out and telling Vivienne's boyfriend to get out of the way. Silly? Yes. Hilarious? Also, yes.
And in the scene immediately after that, Elle's bunny ears flopping down to her face as she tells Emmett to hit her head with a rock.
This bit, when all of Elle's sorority sisters are concerned for her after Warner dumps her.
Pilar: I think he should be shot! Serena: And let me tell you what — I don't think he's all that hot. Margot: I do! Serena: Yeah, well, you're a slut.
