Leonard Nimoy credited as playing...
Mr. Spock
- Lieutenant Dave Bailey: It's blocking the way!
- Mr. Spock: Quite unnecessary to raise your voice, Mr. Bailey.
- Mr. Spock: Has it occurred to you that there is a certain... inefficiency in constantly questioning me on things you've already made up your mind about?
- Capt. Kirk: It gives me emotional security.
- Lieutenant Dave Bailey: Raising my voice back there doesn't mean I was scared or couldn't do my job, it means I happen to have a human thing called an adrenalin gland.
- Mr. Spock: That sounds most inconvenient, however. Have you considered having it removed?
- Lieutenant Dave Bailey: [sees Sulu quietly laughing at him] Very funny.
- Sulu: Try and cross brains with Spock, he'll cut you to pieces every time.
- Capt. Kirk: There must be SOMETHING to do. Something I've overlooked.
- Mr. Spock: Chess: When one is outmatched the game is over. Checkmate.
- Capt. Kirk: Is that your BEST recommendation?
- Mr. Spock: I'm s... I regret that I can find no other logical alternative.
- Mr. Spock: I regret not having learned more about this Balok. In some manner, he was reminiscent of my father.
- Lt. Cmdr. Montgomery 'Scotty' Scott: Then may Heaven have helped your mother.
- Mr. Spock: A very interesting game, this poker.
- Capt. Kirk: It does have advantages over chess.
- Dr. McCoy: Love to teach it to ya.
- Mr. Spock: I believe it adds up to either one of two possibilities: First, a space buoy of some kind.
- Capt. Kirk: Second?
- Mr. Spock: Flypaper.
