Dr. McCoy
- Dr. McCoy: You're BOTH out of your heads!
- Scott: Aye, sir.
- Captain James T. Kirk: And you're on the edge of insubordination!
- Dr. McCoy: I'd be on the edge of insubordination to remind the captain that this smells of something happening to him that I might not be able to patch back together again.
- Scott: Aye!
- Dr. McCoy: What's all this poppycock about life-forms on this planet, Spock? The surface is molten lava, the atmosphere is poisonous...
- Dr. McCoy: Just what was that you locked onto before you beamed him aboard?
- Scott: Ya heard Mr. Spock yourself - "mineral" he called it, like living rock.
- Dr. McCoy: And that became Lincoln?
- Scott: I couldn't tell. May have been another figure down there standing by. What do you make if it?
- Dr. McCoy: I'm not quite sure.
