Leonard Nimoy: Mister Spock

Quotes 

• Mr. Spock : [referring to Captain Christopher]  We cannot return him to Earth, Captain. He already knows too much about us and is learning more. I do not specifically refer to Captain Christopher; but suppose an unscrupulous man were to gain certain knowledge of man's future. Such a man could manipulate key industries, stocks, and even nations, and in so doing, change what must be. And if it is changed, Captain, you and I, and all that we know, might not even exist.

  Capt. Kirk : Your logic can be most... annoying.

• Capt. Kirk : Captain's log, supplemental. Engineering Officer Scott informs, warp engines damaged, but can be made operational and re-energized.

  Enterprise Computer : Computed and recorded, dear.

  Capt. Kirk : Computer, you will not address me in that manner. Compute.

  Enterprise Computer : Computed... dear.

  Capt. Kirk : Mr. Spock, I ordered this computer and its interlinking systems repaired.

  Mr. 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.

  Capt. Kirk : I wouldn't mind so much if only it didn't get so... affectionate.

  Mr. Spock : It also has an unfortunate tendency to giggle.

• Captain John Christopher : I never have believed in little green men.

  Mr. Spock : Neither have I.

• Mr. Spock : I made an error in my computations.

  Dr. McCoy : Oh? This could be an historic occasion.

• Radio Broadcaster : This is the 5.30 news summary. Cape Kennedy. The first manned moon shot is scheduled for Wednesday, 6 a.m. Eastern Standard Time. All three astronauts who are to make this historic...

  [Kirk has the broadcast muted] 

  Capt. Kirk : Manned moon shot? That was in the late 1960s.

  Mr. Spock : Apparently, Captain, so are we.

• Captain John Christopher : I take it that a lady computer is not routine.

  Mr. Spock : We'd put into Cygnet XIV for general repair and maintenance. Cygnet XIV is a planet dominated by women. They seemed to feel the ship's computer system lacked the personality. They gave it one. Female, of course.

  Captain John Christopher : [laughing]  Well, you, you people certainly have interesting problems. I'd, uh... I'd love to stay around to see how your girlfriend works out, but...

• Captain John Christopher : You don't trust me, Spock.

  Mr. Spock : In fact, I do. But only to a certain point.

• Mr. Spock : Captain. Our tractor beam caught and crushed an Air Force plane. It'll be impossible to explain this as anything other than a genuine UFO, possibly alien, definitely destructive.

• [a guard has just been beamed up to the Enterprise] 

  Capt. Kirk : [over communicator]  Your surprise package is an Air Police sergeant from the base. I want you to keep him in the transporter room. No sense in letting him see any more of the ship than is necessary.

  Mr. Spock : [regarding the "paralyzed" sergeant]  I don't believe there'll be any trouble in that respect, Captain. Our guest seems quite satisfied to remain where he is.

• [the bridge crew is picking itself up after being thrown through the time warp; the lights are out] 

  Mr. Spock : Except for secondary systems, everything is out, sir. We're on impulse power only.

  Capt. Kirk : Auxiliaries?

  Mr. Spock : If Mr. Scott is still with us, auxiliaries should be on momentarily.

  [both are attending to Uhura, when the lights come back on] 

  Mr. Spock : Mr. Scott is still with us.
