Scotty: It’s a shame for a good Scotsman to admit it, but I’m not up on Milton.
Kirk: The statement Lucifer made when he fell into the pit. “It is better to rule in hell than serve in heaven.”
Spock: It would be interesting, Captain, to return to that world in a hundred years and to learn what crop has sprung from the seed you planted today.
Kirk: Yes, Mister Spock, it would indeed.
Star Trek – Season 1: Episode 24 – “Space Seed”
Kirk: You ready, Bones?
McCoy: No. I signed aboard this ship to practice medicine, not to have my atoms scattered back and forth across space by this gadget.
Kirk: You’re an old-fashioned boy, McCoy.
Star Trek – Season 1: Episode 24 – “Space Seed”
Kirk: I thought you said it couldn’t possibly be an Earth vessel.
Spock: I fail to understand why it always gives you pleasure to see me proven wrong.
Kirk: An emotional Earth weakness of mine.

Fellini: What is that? Is that a uniform of some kind?
Kirk: This little thing? Just something I slipped on.
Star Trek – Season 1: Episode 21 – “Yesterday is Tomorrow”
Kirk: You said you had some additional information, Mister Spock?
Spock: I made an error in my computations.
McCoy: Oh? This could be an historic occasion.

Mccoy: Maybe he could be retrained, reeducated.
Kirk: Now you’re sounding like Spock.
Mccoy: If you’re going to get nasty, I’m going to leave.

Computer: Computed and recorded, dear.
Kirk: Computer, you will not address me in that manner. Compute.
Computer: Computed, dear.
Kirk: Mister Spock, I ordered this computer and its interlinking systems repaired.
Spock: I have investigated it, Captain. To correct the fault will require an overhaul of the entire computer system and a minimum of three weeks at a Starbase.
Kirk: I wouldn’t mind so much if it didn’t get so affectionate.
Spock: It also has an unfortunate tendency to giggle.
Star Trek – Season 1: Episode 21 – “Tomorrow is Yesterday”
Spock: I picked this up from Doctor McCoy’s log. We have a crew member aboard who’s showing signs of stress and fatigue. Reaction time down nine to twelve percent, associational reading norm minus three.
Kirk: That’s much too low a rating.
Spock: He’s becoming irritable and quarrelsome, yet he refuses to take rest and rehabilitation. Now, He has that right, but we’ve found
Kirk: A crewman’s right ends where the safety of the ship begins. That man will go a shore on my orders. What’s his name?
Spock: James Kirk. Enjoy yourself, Captain.
Star Trek – Season 1: Episode 17 – “Shore Leave”
Kirk: Mister Spock.
Spock: Captain.
Kirk: There’s really something I don’t understand about all of this. Maybe you can explain it to me. Logically, of course. When you jettisoned the fuel and ignited it, you knew there was virtually no chance of it being seen, yet you did it anyhow. That would seem to me to be an act of desperation.
Spock: Quite correct, Captain.
Kirk: Now we all know, and I’m sure the doctor will agree with me, that desperation is a highly emotional state of mind. How does your well-known logic explain that?
Spock: Quite simply, Captain. I examined the problem from all angles, and it was plainly hopeless. Logic informed me that under the circumstances, the only possible action would have to be one of desperation. Logical decision, logically arrived at.
Kirk: I see. You mean you reasoned that it was time for an emotional outburst.
Spock: Well, I wouldn’t put it in exactly those terms, Captain, but those are essentially the facts.
Kirk: You’re not going to admit that for the first time in your life, you committed a purely human emotional act?
Spock: No, sir.
Kirk: Mister Spock, you’re a stubborn man.
Spock: Yes, sir.
Star Trek – Season 1: Episode 13 – “The Galileo Seven”
Spock: Check.
Kirk: Checkmate.
Spock: Your illogical approach to chess does have its advantages on occasion, Captain.
Kirk: I’d prefer to call it inspired.
Spock: As you wish.
