- Tyler's line: "I'm six-five, 220 pounds, and there's two of me!"
- And his rant about drug dealing while Cameron's on the phone with their dad's lawyer, forcing Cameron to quickly cover the mouthpiece.
- The scene where Christy sets the silk scarf Eduardo just gave her on fire and drops it on his bed. The look on his face when he turns around is priceless.Christy: When have you even seen me wear a scarf?Eduardo: This could be the first.
Christy: You're going back there already?Eduardo: Yes! *beat* And also I'm breaking up with you!
- Also the terrified look on his face as he breaks up with her, the tone of his voice sounding like he expects her to deck him at any second.
- After extinguishing the fire (which, if left unchecked, could have set the entire bed and then the room on fire), Eduardo tells Mark he'll be going to San Francisco, hangs up the phone... and Christy's standing right behind him. She has this pouty, puppy-dog look, as if she hadn't just, y'know, set something on fire.
- How about Eduardo protesting that he doesn't know how to change his relationship status on Facebook? Hee!
- The whole character of Christy, really. She looked so serious and genuinely worried about Eduardo not changing his relationship status on Facebook, and seemed flatly ignorant of the fact that he had just been played out by Zuckerberg and Parker. Poor Eduardo had come to realise he wasn't quite right about Asian girls being so ideal, but it is played for laughs.
- A lot of the stuff with Eduardo and the chicken, which the movie thankfully acknowledges is quite ridiculous and sometimes plays it for laughs despite it still be a rather important/serious part of the story. Some gems:
- Eduardo: "I did not torture the chicken! I don't torture chickens!"
- Next thing I know they're accusing me of forced cannibalism!
- Eduardo (defending his actions): "DON'T FISH EAT OTHER FISH?! Th-th-the marlins, and the trouts!?"
- And don't miss Joe Mazzello's awesomely deadpan "(pause) What's he talking about?" in response to that line.
- Sean (after Mark and Eduardo mention the chickens 5 times in a row): "Seriously, what the hell's the chicken?"
- Eduardo: "I did not torture the chicken! I don't torture chickens!"
- Mark facetiously referring to the Winklevoss twin as the "Winklevii" - apparently, Mark Zuckerberg studied Latin in real life.
- The guys using a zipline on the roof for diving into the pool...and promptly taking out half of the chimney due to weight.
- This encounter between a girl who keeps getting the same link in her e-mail and her friend.KC: Seven different people spammed me the same link.KC's friend: What is it?KC: I don't know, but I really hope it's cats that look like Hitler, 'cause I can never get enough of that.
- Mark's disdain at the looping video of the Niagara Falls at "Caribbean Night", flatly stating that it has nothing to do with the Caribbean.
- Eduardo and Mark, after hooking up with their respective flings in the bathroom stalls, looking sheepishly gleeful. "We have groupies!"
- Mark, after getting the relationship status idea, running back to his room in the snow while wearing flip flops and jumping slightly from the cold
- YMMV, but "SORRY! My Prada's at the cleaners! Along with my hoodie and my fuck you flip-flops, YOU PRETENTIOUS DOUCHEBAG." Doubles as a CMOA.
- Mark's "Then I guess that would be the first time somebody's lied under oath!" near the beginning.
- The scene where Mark pulls out a notepad during Eduardo's deposition to double-check the extremely basic arithmetic that Gretchen had just spent three questions on.
- Just for note, the equation is $1,000 + 18,000 = 19,000. And, yes, Mark got the same result if you were curious.
- Mark perjuring himself when it's pointed out his "best friend" is suing him, just to be snarky.I didn't know that. Tell me more.
- The entire scene in Larry Summers' office, especially:Larry Summers: (after listening to Cameron explain why he & Tyler are there) Anne?Anne, Summers' secretary: Yes, sir?Summers: Punch me in the face. (to Tyler) Go ahead.
Summers: I don't know [why they're here] but from the looks of things, they're about to try to sell me a Brooks Brothers franchise.
- Even before that:
Summers: You enter into a code of ethics with the university, not with each other.Tyler: I'm sorry, President Summers, but what you just said makes no sense to me at all.Summers: I'm devastated by that.
- As well as:
Tyler: This idea is potentially worth millions of dollars.Summers: Millions?Cameron: Yes!Summers: You might just be letting your imaginations run away with you.Tyler: Sir, I honestly don't think you're in any position to make that callSummers: I was the US Treasury Secretary. I'm in some position to make that call.
- And also:
"Whoops. Broke a three-hundred thirty-five year old doorknob." (tosses doorknob onto desk before leaving)
- And definitely the reaction of the brothers at the end, in response to to Summer's dismissal and his secretary previously berated them while sitting in chairs about the age of the building:
- A student completely missing the fact that the guy who'd just spent hours giving a presentation was Bill Gates, even when he said the next Bill Gates could be in the room. Listen closely and you'll hear one of his friends threaten to shoot him with a Glock. Made even better by the audible car screech in between "I didn't even know who the speaker was." and "It was Bill Gates"."Are you medically stupid?"
- The Hypocritical Humor in the scene between Sean and Amy; when he pretends he doesn't know her name, she starts to get pissed off, only to be surprised when he introduces himself as Sean Parker, showing that she had no idea what his name was either.
Amy: You're not like fifteen years old or anything, are you?Sean: [Chuckling] No. [Concerned] Wait, you're not like fifteen, are you?
- And this little exchange from the same scene:
- "You know, this is where they filmed Towering Inferno." "... That's comforting."
- In the beginning when the Facemash business shuts down the Harvard server, Dustin goes to check his computer to confirm what the guys saw on Mark's. For a split second you can see the excitement on his face (if not his body language) as he leaves his spot at Mark's chair, then it becomes obvious a few seconds later. It's pretty amusing in its own simple way.
- The Smash Cut between all of the meat-headed men laughing and having fun with Facemash to a single group of women quietly scowling at it in disgust, complete with the music momentarily dropping out.
- Sean, the founder of Napster, talks about how Napster beat the music industry. Eduardo points out that the music industry beat Napster in court. Sean then brings up the now-defuct Tower Records, shutting Eduardo up.
- After the boat race that the Winklevoss twins lose by inches, they just look at the winners celebrating, dismissively go "whatever", and leave the room like they lost horribly.
