SPOCK: Your move, Captain.
KIRK: We should have intercepted by now. The Bridge said they'd call.
SPOCK: I'll have you checkmated your next move.
KIRK: Have I ever mentioned you play a very irritating game of chess, Mister Spock?
SPOCK: Irritating? Ah, yes. One of your Earth emotions.
KIRK: Certain you don't know what irritation is?
SPOCK: The fact one of my ancestors married a human female
KIRK: Terrible having bad blood like that.
KELSO [on monitor] Bridge to briefing lounge. Object is now within tractor beam range.
KIRK: No visual contact, Mister Kelso?
KELSO [on monitor]: No, sir. It's too small to be a vessel. It only reads about one metre in diameter.
SPOCK: Not large enough even for a lifeboat.
KELSO [on monitor] Small enough to bring it aboard, sir, if you want to risk it.
KIRK: Lock onto it, Mister Kelso.
