Larry David is heard but not seen in this episode. In the scene on the beach, he delivers the line, "Is anyone here a marine biologist?!"
George starts walking towards the water, and once he starts wading in, his pantlegs have miraculously been rolled up.
George is telling the story of his encounter with the whale... the whale let out a great bellow and George calms the whale "easy big fella". As he says this, Elaine has her arm resting on the table. A split second later, her arm is upright. Minor goof.
Kramer: (points to his head) I've got all my appointments right up here.
Elaine: What, are you in a bad mood?
Jerry: I got my laundry back.
Elaine: Golden Boy?
Jerry: He didn't make it.
Elaine: I'm sorry.
Jerry: This is Golden Boy's son, Baby Blue.
George: (to Jerry) Why couldn't you make me an architect? You know I always wanted to pretend that I was an architect.
Jerry: (trying to make George look good) He's working on lowering the cholesterol level in whales. All that blubber, it's quite unhealthy. You know, it's the largest mammal on earth. But as George says, they don't have to be.
Jerry: Your mother reads your mail?
Jerry: What do you mean, like postcards?
George: Oh, anything.
Jerry: She doesn't open.
George: She'll open.
Jerry: You've caught your mother opening envelopes?
Jerry: What does she say?
George: I was curious.
Jerry: Isn't that against the law?
George: Maybe I can get her locked up.
Jerry: Six years I've had this t-shirt. It's my best one. I call him Golden Boy.
Jerry: Did you know that the original title for 'War and Peace' was 'War, What Is It Good For?'
George: The sea was angry that day, my friends - like an old man trying to send back soup in a deli. I got about fifty feet out and suddenly the great beast appeared before me. I tell you he was ten stories high if he was a foot. As if sensing my presence, he let out a great bellow. I said, "Easy, big fella!" And then, as I watched him struggling, I realized that something was obstructing its breathing. From where I was standing, I could see directly into the eye of the great fish.
Kramer: Well, what did you do next?
George: Well then, from out of nowhere, a huge tidal wave lifted me, tossed me like a cork, and I found myself right on top of him - face to face with the blowhole. I could barely see from the waves crashing down upon me but I knew something was there. So I reached my hand in, felt around, and pulled out the obstruction.
(George reveals the obstruction to be a golf ball)
Kramer: What is that, a Titleist?
Kramer: Hole in one, huh?
George: (to Jerry) It's one thing if I make it up. I know what I'm doing; I know my alleys. You got me in the Galapagos Islands living with the turtles. I don't know where the hell I am!
George: Then of course with evolution, the octopus lost the nostrils and took on the more familiar look that we know today.
Kramer: Hey... Who wants to have some fun?
Jerry/George: I do!
Kramer: Now are you just saying you want to have fun, or do you really want to have fun?
Jerry: I really want to have fun!
George: I'm just saying I want to have some fun.
Kramer: I've got five hundred Titleists that I got from the driving range in the trunk of my car. Why don't we drive out to Rockaway, and hit 'em.... into the ocean! Picture this: we find a nice sweet spot between the dunes, take out our drivers, we tee up, and poof! The ball goes sailing up into the sky, holds there for a moment, and then: uggh!
George: As I made my way past the breakers, a sudden calm came over me. I don't know if it was divine intervention, or the kinship of all living things. But I tell you Jerry, at that moment, I was a marine biologist.
Diane: What's going on over here?
Woman: There's a beached whale, she's dying.
Man: (yelling) Is anyone here a marine biologist?
George: It was at that moment I decided to tell her that I was not a marine biologist.
Jerry: Wow! What did she say?
George: She told me to go to hell and I took the bus home.
Rosiland Allen (who plays Diane in this ep) played Wendy Smith on Seaquest DSV, a show about a submarine that has a dolphin crew member - and this episode centers around George pretending to be a marine bioligist to date her.
Jerry: The original title of "War and Peace" was War, what is it good for?
War is a soul song written by Edwin Starr that protests the war in Vietnam. Jerry cited the first line of the song.
George: I'm working on my Jack Nicholson. 'You can't handle the truth!'
"You can't handle the truth!" was Jack Nicholson's famous line from the 1992 film "A Few Good Men".
