McCoy: A negative attitude is no good to us. We can’t just leave them out there, wherever they are.
Spock: We shall continue sensor scans, Doctor. At the moment, that is all we can do, except hope for a rational explanation.
McCoy: Hope? I always thought that was a human failing, Mister Spock.
Spock: True, Doctor. Constant exposure does result in a certain degree of contamination.
Star Trek — Season 2: Episode 17 — “The Gamesters of Triskelion”
Spock: Doctor, if I were able to show emotion, your new infatuation with that term would begin to annoy me.
McCoy: What term? Logic? Medical men are trained in logic, Mister Spock.
Spock: Really, Doctor, I had no idea they were trained. Watching you, I assumed it was trial and error.
Star Trek — Season 2: Episode 14 — “Bread and Circuses”
McCoy: What’s the matter, Spock?
Spock: There’s something disquieting about these creatures.
McCoy: Don’t tell me you’ve got a feeling.
Spock: Don’t be insulting, Doctor. They remind me of the lilies of the field. They toil not, neither do they spin. But they seem to eat a great deal. I see no practical use for them.
McCoy: Does everything have to have a practical use for you? They’re nice, soft, and furry, and they make a pleasant sound.
Spock: So would an ermine violin, but I see no advantage in having one.
McCoy: It’s 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.
McCoy: Spock, I don’t know too much about these little tribbles yet, but there’s one thing that I have discovered.
Spock: What is that, Doctor?
McCoy: I like them… better than I like you.
Spock: Doctor?
McCoy: Yes?
Spock: They do have one redeeming characteristic.
McCoy: What’s that?
Spock: They do not talk too much. If you’ll excuse me, sir.
Star Trek — Season 2: Episode 13 — “The Trouble with Tribbles”
Spock: Its trilling seems to have a tranquilizing effect on the Human nervous system. Fortunately, of course… I am immune… to its… effect.
Star Trek — Season 2: Episode 13 — “The Trouble with Tribbles”
Spock: The child was named Leonard James Akaar?
McCoy: Has a kind of a ring to it, don’t you think, James?
Kirk: Yes. I think it’s a name destined to go down in galactic history, Leonard. What do you think, Spock?
Spock: I think you’re both going to be insufferably pleased with yourselves for at least a month… sir.
Star Trek — Season 2: Episode 3 — “Friday’s Child”
Edith: You know as well as I do how out of place you two are around here.
Spock: Interesting. Where would you estimate we belong, Miss Keeler?
Edith: You? At his side, as if you’ve always been there and always will. And you? You belong in another place. I don’t know where or how. I’ll figure it out eventually.
Spock: I’ll finish with the furnace.
Edith: …Captain. Even when he doesn’t say it, he does.
Star Trek — Season 1: Episode 28 — “The City on the Edge of Forever”
Kirk: You were actually enjoying my predicament back there. At times, you seem quite human.
Spock: Captain, I hardly believe that insults are within your prerogative as my commanding officer.
Kirk: Sorry.
Star Trek — Season 1: Episode 28 — “The City on the Edge of Forever”
Spock: A time portal, Captain. A gateway to other times and dimensions, if I’m correct.
Guardian: As correct as possible for you. Your science knowledge is obviously primitive.
Spock: Really?
Kirk: Annoyed, Spock?
Star Trek — Season 1: Episode 28 — “The City on the Edge of Forever”
Kirk: What would you say the odds on our getting out of here?
Spock: Difficult to be precise, Captain. I should say approximately 7,824.7 to 1.
Kirk: Difficult to be precise? 7,824 to 1?
Spock: 7,824.7 to 1.
Kirk: That’s a pretty close approximation.
Spock: I endeavour to be accurate.
Kirk: You do quite well.
Star Trek — Season 1: Episode 27 — “Errand of Mercy”
Kirk: Well, there it is. War. We didn’t want it, but we’ve got it.
Spock: Curious how often you humans manage to obtain that which you do not want.
