Dr. McCoy: He's dead, Jim.
Quotes from DeForest Kelley movies and TV shows
The Trouble With Tribbles - S2-E15
Capt. Kirk: I want to know what killed these tribbles.
Dr. McCoy: I haven't figured out what keeps them alive yet.
[In sickbay]
Spock: Doctor, I think I'll return to my station now.
Dr. McCoy: You ARE at your station, Mr. Spock!
Capt. Kirk: Dr. McCoy, I believe you're enjoying all this.
Spock: Indeed, Captain. I've never seen him look so happy.
Dr. McCoy: [To Spock] Shut up!
[Kirk opens his mouth to comment, but McCoy interrupts.]
Dr. McCoy: Shh! Shh!
[Dejected, Kirk lies back.]
Dr. McCoy: [Grinning] Well, what do you know? I finally got the last word.
Dr. McCoy: I'm a doctor, not a bricklayer.
The Trouble With Tribbles - S2-E15
Dr. McCoy: It is 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.
Dr. McCoy: Spock, I do not know too much about these little Tribbles yet, but there is one thing that I have discovered.
Spock: What is that, Doctor?
Dr. McCoy: I like them... Better than I like you.
Dr. McCoy: Spock, I've always suspected that you were a little more human than you let on. Mrs. Sarek, I know about the rigorous training of the Vulcan youth, but tell me, did he ever run and play like the human children, even in secret?
Amanda: Well, he, uh...he did have a pet Sehlat he was very fond of.
Dr. McCoy: Sehlat?
Amanda: It's sort of a...a fat Teddy bear.
Dr. McCoy: [Amused] A Teddy bear? [Sarek comes and takes Amanda away.] A Teddy bear [to Kirk].
Spock: Not precisely, Doctor. On Vulcan, the Teddy bears are alive...and have six inch fangs.
Operation -- Annihilate! - S1-E30
Dr. McCoy: [In an aside to Kirk] Please don't tell Spock I said he was the best first officer in the fleet.
Spock: Why, thank you, Doctor McCoy.
Capt. Kirk: You were so concerned about his Vulcan eyes, Doctor, you forgot about his Vulcan ears.
Dr. McCoy: I'm a doctor, not an engineer.
The Man Trap - S1-E2
Dr. McCoy: I thought it was, Sir... Another error on my part.
Capt. Kirk: I'm not counting them, Bones. (00:15:22)
McCoy: Yes! Genesis! How can you be deaf with ears like that?!
God Being: It is I. The journey you undertook to reach me could not have been an easy one.
Sybok: It was not! The barrier stood between us, but we breached it!
God Being: Magnificent! You're the first to find me.
Sybok: We sought only your infinite wisdom!
God Being: And how did you breach the barrier?
Sybok: With a starship.
God Being: This starship, could it carry my wisdom beyond the barrier?
Sybok: It could, yes!
God Being: Then I shall make use of this starship.
Sybok: It will be your chariot!
James Kirk: Excuse me.
God Being: It will carry my power to every corner of creation!
James Kirk: Excuse me, I'd just like to ask a question. What does God need with a starship?
God Being: Bring the ship closer.
James Kirk: I said, what does God need with a starship?
Dr. McCoy: Jim, what are you doing?
James Kirk: I'm asking a question.
God Being: Who is this creature?
James Kirk: Who am I? Don't you know? Aren't you God?
Sybok: He has his doubts.
God Being: You doubt me?
Chang: I am constant as the northern star!
McCoy: I'd give real money if he'd shut up.
