I was recently think about the Firefly series. There is hardly an episode without a memorable quote. One my favorites comes after the sword fight.
Harrow: "You have to finish it, lad. You have to finish it. For a man to lay beaten... and yet breathing? It makes him a coward."
Inara: "It's humiliation."
Mal: "Sure. It would be humiliating. Having to lie there while the better man refuses to spill your blood. Mercy is the mark of a great man. (lightly stabs Atherton with the sword) Guess I'm just a good man. (stabs him again) Well, I'm all right."
