- The moment when Hooper visits the Brody household with some wine as a souvenir. Martin, fed up with the whole shark problem, starts filling his pint with the wine despite Hooper's protests that he should let it breathe. Then, he gives Ellen and Hooper the smallest amount imaginable.
- To be fair, Hooper did actually hold up two fingers as a way to tell Brody to stop filling his glass. Clearly, neither of them wanted too much, anyway.
- And it's the red wine, even though they're having fish.
- And two scenes later, he's working his way through the other bottle.
- "My husband tells me you're in sharks."
- This exchange:
Ellen: Martin hates boats. Martin hates water. Martin - Martin sits in his car when we go on the ferry to the mainland. I guess it's a childhood thing. It's a - there's a clinical name for it, isn't there?
- When Quint sees the shark cage, he doubts its reliability, saying "you go in the cage. Cage goes in the water. Shark's in the water," then smiles and starts singing "farewell and adieu to you fair Spanish ladies! Farewell and adieu, you ladies of Spain!"
- At one point, Quint crushes a beer can in his hand, and Hooper responds by doing the same thing with a styrofoam cup.
- "You're gonna need a bigger boat." Even funnier is how the audience knows exactly why Brody is saying that when he finally saw the shark.
- It's even more hilarious once you realize that line was completely ad-libbed.
- As Quint and Hooper drunkenly share battle scars from their various undersea encounters, Brody looks down at his appendectomy scar and decides to keep quiet.
- Hooper revealing his worst scar:
"Mary Ellen Moffett. She broke my heart"
- And the other two men cracking up as not only do they find his joke amusing, they can all empathize.
- Hooper doing his best to talk some sense into the town Mayor... but the Mayor is more worried about the vandalized Welcome to Amity sign covered with shark graffiti.
- The vandalization itself, with a spray-painted shark fin and a speech balloon coming from the beach bunny: "Help, shark!"
- And the hint that these were particularly well-researched vandals, drawing the fin in correct proportion to the woman.
- Might just be a case of the casting not matching the script, but I always found it amusing how everyone treats Hooper like he's a fresh out of college kid. Dude has gray in his beard.
- Dreyfuss was 27 when the film was released, which isn't beyond college age depending on what degree is being pursued, especially in the sciences. Most Ph.D students don't finish their degrees until their late-20s, and even that can be prolonged depending on the research. Also, compared to Shaw and Scheider, he was relatively young. It is true, however, that this was a case of casting not matching the script as the script was adjusted for Dreyfuss.
- And people can start to go grey in even their late teens.
- Quint's treatment of Hooper, in particular, seems to have more to do with white collar vs. blue collar conflict than age. When Quint pejoratively refers to Hooper as a college boy, the implication is that Hooper has led a sheltered life, in contrast to the hard knocks that Quint has experienced.
- Hooper making faces behind◊ Quint's back after a rebuke.
- Brody and his wife are arguing over whether they should let Michael play in the water.
Ellen: Martin, it's his birthday tomorrow!
Brody: I don't want him out on the water!
Ellen: He's not in the water! He's on a boat. I don't think he'll ever go in the water after what happened.
Ellen: Michael! Did you hear your father? Out of the water!
- This exchange:
Brody: It doesn't make sense that they pay a guy like you to watch sharks.
Hooper: It doesn't make sense for someone who's afraid of water to live on an island.
Brody: It's only an island when you look at it from the water.
Hooper: That makes a lot of sense.
- Hooper watching some of the would-be shark-killers: "Ha ha, they're all gonna die."
- A deleted scene finds Quint going to a music store to buy some piano wire... and ends with him yelling Beethoven's "Ode to Joy" at a kid who can't play it on clarinet. Naturally, this exchange comes out of nowhere and is promptly forgotten.
- The horrifying scene of Charlie barely escaping the shark ends on a fairly amusing note. He probably says the most logical thing anyone could say after experiencing such fright:
Charlie: Can we go home now?
- During the scene with the tiger shark, we get this little gem from one of the fisherman:
Fisherman: Well what kind? What kind of shark?
Hooper: Tiger shark!
Fisherman: A what?
- For the last line, it's not so much the quote itself but the tone in which he says it.
- Also, as the journalist is trying to get the fishermen to pose for a picture, Quint can be seen cruising on by in the Orca snickering whilst tipping his hat slightly. Obviously he can tell that they've got the wrong shark!
- Brody's grumbling as he scoops bait into the water. Just before the shark pops up.
- When the shark makes it's first appearance while the trio are out on the Orca, Brody's reaction is to freak out, and Quint's is to prepare to harpoon it. Hooper's reaction is to excitedly grab his camera and start snapping photos, while demanding that Brody get closer to the shark in order to give it a reference point for size. Brody... is not pleased with this plan.
- Hooper's reaction to being plunged into darkness during the night attack.
Hooper: He ate the lights.
