Ok mine:
The Doctor: If they live because of this, then life is worthless.
Novice Hame: But who are you to decide that?
The Doctor: I'm The Doctor. And if you don't like it, if you want to take it to a higher authority: there isn't one. It stops with me.- Ten & Novice Hame, New Earth
Doctor: (Shouting through a loudspeaker) Come on, look at me! No plan, no back up, no weapons worth a damn, oh, and something else I don't have, anything to lose! So, if you're sitting up there in your silly little space ships with all your silly little guns, and you've got any plans on taking the Pandorica tonight, just remember who's standing in your way! Remember every black day I ever stopped you, and then, and then, do the smart thing! (pause) Let somebody else try first.- Eleven, The Pandorica Opens
I'll be back with more at some point but these were the first 2 that came to mind
