“Madame Kovarian: The anger of a good man is not a problem. Good men have too many rules.The Doctor: Good men don't need rules. Today is not the day to find out why I have so many.”

“The Doctor: It's my nose; it has special powers.Nancy: Yeah? That why it's so...?The Doctor: What?Nancy: Nothing.The Doctor: What?Nancy: Nothing. Do your ears have special powers too?”

“Demons run when a good man goes to warNight will fall and drown the sunWhen a good man goes to warFriendship dies and true love liesNight will fall and the dark will riseWhen a good man goes to warDemons run, but count the costThe battle's won, but the child is lost”

“Rule 1: The Doctor lies.”

“Young Reinette: Monsieur, be careful!The Doctor: It's just a nightmare, Reinette, don't worry, everyone has nightmares. Even monsters under the bed have nightmares!Young Reinette: What do monsters have nightmares about?The Doctor: Me!”

“When you run with the Doctor, it feels like it'll never end. But however hard you try you can't run forever. Everybody knows that everybody dies and nobody knows it like the Doctor. But I do think that all the skies of all the worlds might just turn dark if he ever for one moment, accepts it. Everybody knows that everybody dies. But not every day. Not today. Some days are special. Some days are so, so blessed. Some days, nobody dies at all. (In the library, the Doctor walks back to the TARDIS. He stops, looking at the doors. Then he raises his hand, and stands there poised like that for a long moment. Finally he snaps his fingers. The doors open. He smiles slowly and walks in, joining Donna. Then he snaps his fingers again, and the doors close. River's voice continues over this.) Now and then, every once in a very long while, every day in a million days, when the wind stands fair, and the Doctor comes to call... everybody lives.”

“The Doctor: This is bad, I don't like this. [kicks console and yells in pain] Never use force, you just embarrass yourself. Unless you're cross, in which case... always use force! Amy: Shall I run and get the manual? The Doctor: I threw it in a supernova. Amy: You threw the manual in a supernova? Why? The Doctor: Because I disagreed with it! Now stop talking to me when I'm cross!”
