“[The Doctor] pulled the thing out of Prince Boris's mouth, waving it around. 'Oh. Blimey. This is not a spatula. What is it?'I [Amy] stared at the stubby thing. It looked like the world's chunkiest novelty gift pen... I coughed. 'That, Doctor, is the sonic screwdriver.''Ah,' Dr Smith boggled. 'Right. Is it? Oh dear.' Another pause. 'What does it do?''Well... it screws things... sonically. On a good day, we fight off monsters with it.''Monsters, eh?' Dr Smith nodded gravely and... pointed it at the doorway like a gun and said, hopefully, 'Pew! Pew! Pew!' He turned back to me. 'Like that?''Other way up,' I said gently.”

“Oh, and I [Amy] may also have told him that I quite fancied Dr Smith [The Doctor]. Which in the 1780s was probably punishable by stoning or corsets.”

“ Dalek Sec: The Doctor will open the Ark! The Doctor: Ha ha, the Doctor will not. Dalek Sec: You have no way of resisting! The Doctor: Mm, you got me there.

Harmless is just the word: that's why I like it! Doesn't kill, doesn't wound, doesn't maim. But I'll tell you what it does do: It is very good at opening doors. [He pushes the switch and the doors explode inwards; Jake's squad and some Cybermen run in and open fire.] ”

“The whole feeling-out-of-my-element thing was pissing me off, and then I had Pepé Le Pew over there threatening my death.”

“Ronkers was getting out of the elevator on the first floor when the intercom paged 'Dr Heart'. There was no Dr Heart at University Hospital. 'Dr Heart' meant someone's heart had stopped.'Dr Heart?' the intercom asked sweetly. 'Please come to 304 . . .'Any doctor in the hospital was supposed to hurry to that room. There was an unwritten rule that you looked around and made a slow move to the nearest elevator, hoping another doctor would beat you to the patient. Ronkers hesitated, letting the elevator door close. He pushed the button again, but the elevator was already moving up.'Dr Heart, room 304,' the intercom said calmly. It was better than urgently crying, 'A doctor! Any doctor to room 304! Oh my God, hurry!' That might disturb the other patients and the visitors.”

“Drinking is such a necessity to human life that people cannot fathom an individual who, like a child confined to a church pew, gets little enjoyment out of it and would rather do other things.”
