“Demons run when a good man goes to war
Night will fall and drown the sun
When a good man goes to war

Friendship dies and true love lies
Night will fall and the dark will rise
When a good man goes to war

Demons run, but count the cost
The battle's won, but the child is lost”

“The Doctor: Don't blink. Don't even blink. Blink and you're dead. Don't turn your back. Don't look away. And don't blink.”

“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!”

“River Song: Use the stabilisers!
The Doctor: It doesn't have stabilisers!
River Song: The blue switches!
The Doctor: The blue ones don't do anything, they're just... blue!
River Song: Yes they're blue: they're the blue stabilisers! [presses the button and the TARDIS indeed stabilises] See?
The Doctor: Yeah? Well, it's boring now, isn't it? They're boring-ers! They're blue... boring-ers!
Amy: Doctor, how come she can fly the TARDIS?
The Doctor: You call that flying the TARDIS? [scoffs] Ha!
River Song: Okay, I've mapped the probability vectors, done a foldback on the temporal isometry, charted the ship to its destination and... [presses a button, the cloister bell clangs] parked us right alongside.
The Doctor: Parked us? But we haven't landed!
River Song: Of course we've landed; I just landed her.
The Doctor: But it didn't make the noise.
River Song: What noise?
The Doctor: You know, the... [does an impression of the TARDIS materialisation sound]
River Song: It's not supposed to make that noise. You leave the brakes on.
The Doctor: Yes, well, it's a brilliant noise. I love that noise.”
