- When Nedry and Dodgson meet before Nedry leaves for the park:
Dodgson: You shouldn't use my name.
(waving his hands and pointing) Dodgson! Dodgson! We've got Dodgson here! (beat)
See? Nobody cares.
- In the iconic scene where everyone sees their first live dinosaur, Ellie is very preoccupied with the leaf of an extinct plant she picked up. Finally, Grant grabs her head and physically makes her look. Cue dropped jaw...
- From early on:
Ellie: What are you thinking?
Alan: That we're out of a job.
- Reality Subtext: That was inspired by a Real Life statement by head of the original stop-motion animation team hired for the movie when they saw the initial CGI work.
- The robot arm in the dinosaur nursery taking the hatched egg right out of Grant's hand and setting it back down. The look on his face...
- This gem from early on, after Malcolm, Sattler, and Grant all argue against Jurassic Park:
Hammond: I don't believe it! Hah! I don't believe it! You're supposed to come here and defend me against these characters and the only one I've got on my side is the bloodsucking lawyer!
Gennaro: Thank you.
- Later, when the dinosaur tour falls flat thanks to the non-appearance of the dinosaurs:
Malcolm: Ah, now eventually you do plan to have dinosaurs on your, on your dinosaur tour, right? Hello? (taps the camera lens, breathes on it) Hello? Yes?
Hammond: (deadpan) I really hate that man.
- This famous exchange, but especially right after with Ian and Alan turning to stare at her, and Alan's little smile:
Ian: God creates dinosaurs. God destroys dinosaurs. God creates man. Man destroys god. Man creates dinosaurs.
Ellie: Dinosaurs... eat man. Woman inherits the earth.
- Ian's utterly deadpan reaction to the Triceratops feces:
"That is one big pile of shit."
- Gennaro bolts upon seeing the T. rex and hides in a toilet cubicle. Alan and Ian see this, but not the T. rex.
Alan: Where does he think he's going?
Ian: When you gotta go, you gotta go.
- After Grant retrieves Tim from a car stuck in a tree, the branches snap and the car comes loose, crashing down through the tree and landing on top of them (luckily the roof was missing, creating a safe spot), and then...
Tim: Well...we're back...in the car again.
Grant: At least you're out of the tree.
- Later, everyone has to climb a tree to stay safe for the night. Tim objects.
Lex: (trees) don't bother me.
Tim: Yeah, well you weren't in the last one.
- The moment when Lex decides she wants to stroke the Brachiosaurus after seeing Grant and Tim do it... and it promptly sneezes all over her.
Tim: God bless you!
- Hammond's reaction when the park's fences begin shutting off:
Check the vending machines."
- When attempting to fix Jurassic Park's computer problem:
Nedry (on computer): Unh-unh-uh, you didn't say the magic word! Unh-unh-uh. Unh-unh-uh...
Arnold: PLEASE! Goddamnit, I hate this hacker crap!
- Ellie and Muldoon discovering the injured Malcolm:
- This exchange:
Hammond: When they opened Disneyland in 1956, nothing worked right.
- When Dennis Nedry slips down the slope after his jeep gets stuck in the rain, there is a cartoonish whoosh clearly audible.
- It's unknown if this was intentional, but towards the end, one of the jeeps has mud covering parts of the Jurassic Park logo, so it looks like it says, "UR ASS PARK".
- Alan scaring the kids...by pretending the 10,000 volt electric fence is switched on when he touches it.
Lex: (angry) That's not funny.
Tim: (laughing) That was great!
- Nedry attempting to distract the Dilophosaurus... by trying to get it to chase a stick.
Nedry: (as Dilophosaurus stares at him) Ah, no wonder you're extinct! I'm gonna run you over when I come back down!
- At the end as they flee the visitor center:
Grant: Mr. Hammond, after careful consideration I've decided not to endorse your park.
Hammond: So have I.
- Right before that, as the "When Dinosaurs Ruled the Earth" banner flutters down past the Tyrannosaurus.
- When the Tyrannosaurus is chasing a Jeep and it appears in the "Objects in mirror are closer than they appear" mirror. As if it could be any closer already.
- Muldoon's smug expression when the T. rex gives up the chase and Malcolm's "Think they'll have that on the tour?" add a bit of icing to the cake.
- After learning that all the dinosaurs are female.
Ian: So how do we know? Does someone go out into the park and pull up the dinosaur's skirts?
- When the the dinosaurs start rampaging, the protagonists are unable call for help or evacuate because all the phones are down. (courtesy of Nedry's virus.) When they finally reestablish communication, Grant informs Hammond via phone... who fails to comprehend that they can finally leave the island.
- Really, we could just say "Every other line Malcolm says in this movie."
- When trying to tell Ellie where to go to restart the park, Hammond pulls out a map and places it over Malcom's already broken leg, who then gasps in pain. Hammond gives him an apology that doesn't sound quite sincere.
- The blasť way that Ian asks Grant and Ellie about their job, whilst eating peanuts on the helicopter. Made about a hundred times more hilarious by Jeff Goldblum's weirdly fascinating laugh.
- Darkly humorous moment from the first Tyrannosaurus rex scene:
- Nick Van Owen and Eddie Carr's reaction when Kelly is revealed to be Ian's daughter:
Nick Van Owen: (awkwardly, gesturing between the reunited father and daughter) Do you see any family resemblance here?
- When the Tyrannosaurus is rampaging through San Diego: while chasing Malcolm and Harding in their car, San Diego police and Animal Control show up. They have just enough time to get one good look at the T. rex before it roars and they throw their cars into reverse.
- Also in that sequence, Ian and Sarah are trying to get the T. rex's attention so they can lead it back to the boat.
Ian: It's never gonna know we have it unless that thing makes some kind of sound!
Sarah: (the T. rex looks over in their direction) He knows.
(*CRASH* The 76 ball off of the nearby gas station rolls past their car)
- Later, as the T. rex is chasing them, Sarah suggests that Ian should slow down so they don't get too far ahead of the T. rex and lose its attention. Ian takes one glance behind them to see how close the T. rex is and promptly hits the gas harder.
- Also from the T. rex's rampage we have a man doing a Godzilla Shout-Out saying "I left Japan to get away from this" in Japanese.
- During the scene where the T. rex bites the traffic signal, sharp-eyed viewers will notice that the street sign on the right reads "No Skateboards, No Dinosaurs".
- Malcolm asks Nick why he joined Greenpeace. His answer: Women. Malcolm's response: "Noble, very noble."
- When they first get to the island, they go into the jungle and find Sarah's backpack. Ian starts shouting, "Sarah!" and Nick yells, "Sarah Harding!" Ian stops, gives him a look, and asks, "How many Sarahs you think there are on this island?" Gets a call back later — when they're searching for Nick, most of the group is just yelling "Nick!" while Ian absentminded chimes in with, "Nick Van Owen!"
- Roland Tembo has quite a bit of trouble with the pronunciation of the dinosaurs' names.
(chasing dinosaurs on the game trail)
Tembo: You're coming up on a...
(flips through his dinosaur guide)
- And later it seems like his team is having fun with his explanations:
Hunter: Say again, Roland, a what?
Tembo: The one with the big red horn. Pompadour. Elvis!
- When the group, looking for Sarah, finally sees their first dinosaur and naturally, Eddie and Nick are slack-jawed while Ian is unimpressed. Ian asks them why they're so shocked and Nick tries to explain that he didn't really think he'd see actual dinosaurs.
Malcolm: What did you think you were gonna see?
Nick: Animals. Maybe, uh, b-big iguanas.
Malcolm: (shakes his head) Fruitcake.
- The crown jewel, in this troper's opinion, is when Nick, Sarah, and Malcolm are dangling perilously in the trailer about to fall off a cliff and still have time to be sarcastic.
Eddie: (yells down to them) What do you need?
Eddie: Rope! What, anything else?
Malcolm: Yeah! Three cheeseburgers with everything on 'em.
Nick: No onions on mine!
Sarah: And an apple turnover!
- During the T. rex rampage scene, it comes upon the backyard area and starts slurping up the water of a pool. A dog comes and starts barking it but quickly goes back into it's doghouse when the T. rex growls at it. This is followed by a child waking up and seeing it, then going to his parent's bedrooms to tell them. They don't believe him at first, thinking it a usual childhood fear of the dark and eventually go to the bedroom to reassure him there's nothing wrong...until they look out the window and see a T. rex right in of them with the chain of the dog danging from it's mouth along with the doghouse. The parents promptly scream, the child...takes a picture of it.
- When Burke describes the way Pachycephalosaur's skull is extra thick on the top of its head and is purposefully designed for absorbing impact. A second later, the Pachycephalosaurus helpfully demonstrates this point by ramming its head into a car door with enough force to send the two men inside the car crashing out of the windows on the opposite side.
- Ian gets a golden Brick Joke line, after his daughter uses a complicated uneven-bars gymnastics routine to kick a Velociraptor out the window.
Ian: [incredulously] The school cut you from the team?
