Leonard McCoy quotes from Star Trek: The Original Series

Spock

Need any help, Doctor?

McCoy

[struggling in gladiator fight] Whatever gave you that idea?

McCoy

I knew it was wrong, I shouldn't have done it.

Kirk

What's that?

McCoy

I should have never reconnected his mouth.

McCoy

Sickbay to Bridge.

Kirk

What is it. Bones?

McCoy

Well, if all the shouting's over up there, I'd like for you to report to Sickbay.

Kirk

What for?

McCoy

Well, you're due in surgery. I'm going to bob your ears.

Spock

Captain... please go. Somehow they do not look aesthetically agreeable on humans.

McCoy

Well, are you coming, Jim, or do you want to go though life looking like your first officer?

Kirk

I'm on my way!

Spock

Evil does seek to maintain power by suppressing the truth.

McCoy

Or by misleading the innocent.

Captain Kirk. You did not kill. Is this the way of your kind?

Kirk

We fight only when there is no other choice. We prefer the ways of peaceful contact. I speak for a vast alliance of fellow creatures who believe in the same thing. We have sought you out to join us. Our mission is still one of peace.

Approach our planet and be welcome. A delegation will come out to meet you. Our warning threats are over.

Kirk

Excellent. Lieutenant, cancel Red Alert. Mister Chekov, resume original course, warp factor two.

Chekov

Warp factor two, sir.

Spock

Captain. May I ask a question? You needn't answer if it seems too personal.

Kirk

I'm sure I'll be able to give you an answer, Mister Spock

Spock

This afternoon, you wanted to kill, didn't you?

McCoy

But he didn't kill, Mister Spock.

Spock

But he wanted to, Doctor.

Kirk

Is that the way it seemed to you?

Spock

Yes, sir.

Kirk

Mister Spock... you're absolutely right. That's exactly the way it was.

Spock

Mankind. Ready to kill.

Kirk

That's the way it was in 1881.

Spock

I wonder how humanity managed to survive.

Kirk

... We overcame our instinct for violence.

Scotty

What is it [the antidote]?

McCoy

It's a diluted theragen derivative.

Spock

Theragen-- a nerve gas used by the Klingons.

Scotty

Aye, and deadly, too. What are you thinking of, Doc? Are you trying to kill us all?

McCoy

The release of emotions, Mr. Spock, is what keeps us healthy-- emotionally healthy, that is.

Spock

That may be, Doctor. However, I have noted that the healthy release of emotion is frequently very unhealthy for those closest to you.

Spock

We are in a wilderness of arctic characteristics.

McCoy

He means it's cold!

McCoy

Think, Spock – what's happening on your planet right now?

Spock

My people are barbarians... warlike barbarians.

McCoy

Who nearly killed themselves off with their own passions. Spock – you're reverting back to the ways of your ancestors... five thousand years before you were born!

Spock

There's no further need to observe me, Doctor. As you can see, I've returned to the present in every sense.

McCoy

But it did happen, Spock.

Spock

Yes, it happened. But that was five thousand years ago. And she is dead now. Dead and buried. Long ago.
