Quotes Edit

  • Captain Kirk: You have to be either an obsessive crackpot who's escaped from his keeper, or Samuel T. Cogley, attorney at law.


  • Mister Spock: Lieutenant, I am half-Vulcanian. Vulcanians do not speculate. I speak from pure logic. If I let go of a hammer on a planet that has a positive gravity, I need not see it fall to know that it has in fact fallen.



  • Captain Kirk: It's not all bad, Mr. Spock. Who knows, you may be able to beat your next captain at chess.


  • Captain Kirk: Given the same circumstances, I would do the same thing without hesitation. Because the steps I took, in the order I took them, were absolutely necessary, if I were to save my ship. And *nothing* is more important than my ship.
