Spock: Live long and prosper.
Amanda: And you, Sarek, would you also say thank you to your son?
Sarek: I don't understand.
Amanda: Well, for saving your life.
Sarek: Spock acted in the only logical manner open to him. One does not thank logic, Amanda.
Amanda: Logic, logic - I'm sick to death of logic! Do you want to know how I feel about your logic?
Spock: Emotional, isn't she?
Sarek: She has always been that way.
Spock: Indeed? Why did you marry her?
Sarek: At the time, it seemed the logical thing to do.
Spock: Doctor, I think I'll return to my station now.
Dr. McCoy: You ARE at your station, Mr. Spock!
Capt. Kirk: Dr. McCoy, I believe you're enjoying all this.
Spock: Indeed, Captain. I've never seen him look so happy.
Dr. McCoy: [To Spock] Shut up!
[Kirk opens his mouth to comment, but McCoy interrupts.]
Dr. McCoy: Shh! Shh!
[Dejected, Kirk lies back.]
Dr. McCoy: [Grinning] Well, what do you know? I finally got the last word.
Dr. McCoy: He's dead, Jim.
Capt. Kirk: Space, the final frontier. These are the voyages of the starship Enterprise. Its 5-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.
Dr. McCoy: It is a human characteristic to love little animals, especially if they're attractive in some way.
Spock: Doctor, I am well aware of human characteristics. I am frequently inundated by them, but I've trained myself to put up with practically anything.
Dr. McCoy: Spock, I do not know too much about these little Tribbles yet, but there is one thing that I have discovered.
Spock: What is that, Doctor?
Dr. McCoy: I like them... Better than I like you.
Yeoman Janice Rand: Hello Beauregard. How are you today, darling?
Sulu: Her name's Gertrude.
Yeoman Janice Rand: No, it's a he-plant. A girl can tell.
Sulu: Why do people have to call inanimate objects, she? Like um, she's a fast ship.
Yeoman Janice Rand: He is not an inanimate object. He's so animate he makes me nervous. (00:23:21)
Uhura: Message, Captain. Starship based on Current Four requesting explanation of our delay here, sir. Space Commander Dominguez says we have supplies he urgently needs.
Capt. Kirk: Tell Jose he'll get his chili peppers when we get there. Tell him the're prime Mexican reds, I hand-picked them myself. But he won't die if he goes a few more days without them. Got it?
Uhura: Got it, Captain. (00:14:00)
Dr. McCoy: Spock, I've always suspected that you were a little more human than you let on. Mrs. Sarek, I know about the rigorous training of the Vulcan youth, but tell me, did he ever run and play like the human children, even in secret?
Amanda: Well, he, uh...he did have a pet Sehlat he was very fond of.
Dr. McCoy: Sehlat?
Amanda: It's sort of a...a fat Teddy bear.
Dr. McCoy: [Amused] A Teddy bear? [Sarek comes and takes Amanda away.] A Teddy bear [to Kirk].
Spock: Not precisely, Doctor. On Vulcan, the Teddy bears are alive...and have six inch fangs.
Spock:Young man, this is likely to be quite hazardous. If I were you...
Kirk: Hold on, Spock. Out of the mouths of babes...
Kid: Who ya callin' a babe?
Kirk: I'm callin' you a babe.
Kid: You callin' me a babe?
Kirk: Yeah, I'm callin'... [Kid brandishes a knife, Kirk continues.] I'm callin' you a babe, but there's nothing personal. Sit down.
