“The Doctor: Amazing. Nancy: What is? The Doctor: 1941. Right now, not very far from here, the German war machine is rolling up the map of Europe. Country after country, falling like dominoes. Nothing can stop it, nothing. Until one tiny, damp little island says "No. No, not here." A mouse in front of a lion. You're amazing, the lot of you. I don't know what you do to Hitler, but you frighten the hell out of me.”

“Amy Pond: 'I thought... well, I started to think you were just a madman with a box.'The Doctor: 'Amy Pond, there's something you better understand about me, 'cause it's important and one day your life may depend on it. [He Smiles] I am definitely a madman with a box.”

“The Doctor: Just had a fall. All the way down there, right to the library. Heck of a climb back up.Amelia: You're soaking wet. The Doctor: I was in the swimming pool. Amelia: You said you were in the library. The Doctor: So was the swimming pool.”

“Don't play games with me! You just killed someone I like, that is not a safe place to stand! I'm the Doctor, and you're in the biggest library in the Universe. Look me up.”

“The Doctor: You know how adults tell you everything's going to be fine, just to make you feel better? Amelia: Yes. Doctor: Well.....everything's going to be fine.”

“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!”
