McCoy: Yes, Captain?
Kirk: I shouldn't have chewed you out. I'm sorry.
McCoy: I understand.
Spock: Inefficient, however. Emotion, Captain.
Kirk: Yes, you're quite right, Mr. Spock. Inefficient... and illogical.
McCoy: Jim! You touch it, her nearest male relative will have to try to kill you. They're offering you a chance for combat. They consider it more pleasurable than love.
Kirk: If you lead these people now, be certain you make the right decisions.
Kras: Is the new leader of the Ten Tribes afraid? Let me kill him for you.
Kirk: Let the Klingon and me fight. It might amuse you.
Maab: Perhaps to be a Teer is to see in new ways. I begin to like you, Earth man, and I saw fear in the Klingon's eye.
Kras: We had an agreement.
Maab: That, too, may change, Klingon.
Kirk: Do you think we can create a sonic disruption with two of our communicators?
Spock: Only a very slight chance it would work.
Kirk: Well, if you don't think we can, maybe we shouldn't try.
Spock: Captain, I didn't say that exactly.
Kirk: Worried about the delivery?
McCoy: Capellans aren't human, Jim. They're humanoid. There's certain internal differences. I don't have equipment for an emergency.
Kirk: If you don't think you can handle it ...
McCoy: I can do it. The last thing I want around is a ham-handed ship's captain.
McCoy: Look, I'm a doctor, not an escalator!
Kirk: How did you arrange to touch her, Bones, give her a happy pill?
McCoy: No... a right cross.
Kirk: Never seen that in a medical book.
McCoy: It's in mine from now on.
Spock: Fortunately, this bark has suitable tensile cohesion.
Kirk: You mean, it makes a good bowstring.
Spock: I believe I said that.
(offering Spock Eleen's baby)
McCoy: No, no, Mr. Spock, you place this arm under here to support its back and this hand here...
Spock: I would rather... I would rather not. Thank you.
Eleen: McCoy! Bring our child.
Kirk: "Our" child?
McCoy: I'll explain later.
Spock: That should prove very interesting.
Scotty: There's an old, old saying on Earth, Mr. Sulu, "fool me once, shame on you, fool me twice, shame on me".
Chekov: I know this saying, it was invented in Russia.
Kirk: The cavalry doesn't come over the hill in the nick of time anymore.
Spock: If by that you mean we can't expect help from the Enterprise, I must agree.
Spock: "Oochie woochie coochie coo"?
Kirk: An obscure Earth dialect, Mr. Spock. Oochie woochie coochie coo. If you're curious, consult Linguistics.
Spock: Well, at any rate, this should prove interesting.
Spock: When the woman starts explaining how the new High Teer is actually Dr. McCoy's child.
Scotty: What's that again, Mr. Spock?
Kirk: We don't actually understand it ourselves, Mr. Scott.
Spock: Nor does Dr. McCoy.
Spock: The child was named Leonard James Aka'ar?
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.
