Kirk: Bones, did you ever hear of a doomsday machine? McCoy: No. I'm a doctor, not a mechanic. Kirk: It's a weapon built primarily as a bluff. It's never meant to be used.

They don't exist anymore, but the machine is still destroying. — Star Trek: The Original Series, "The Doomsday Machine" Dr. Strangelove: Of course, the whole point of a Doomsday Machine is lost, if you keep it a secret! Why didn't you tell the world, eh?!! Russian Ambassador Sadesky: It was to be announced at the Party Congress on Monday. As you know, the Premier loves surprises. — Dr. Strangelove
