The Doctor: I am being extremely clever up here and there's no one to stand around looking impressed. What's the point in having you all?
The Doctor: And Dr. Song, you've got that face on again.
River Song: What face?
The Doctor: The he's-hot-when-he's-clever face.
River Song: This is my normal face.
The Doctor: Yes it is.
The Doctor: [pinned to the floor of the Oval Office by Secret Service] River! Have you got my scanner working yet?
River Song: [Inside the TARDIS] Oh, I hate him!
The Doctor: No, you don't.
The Doctor: I'm your new undercover agent, on loan from Scotland Yard. Code name, The Doctor. These are my top operatives, The Legs, The Nose, and Mrs. Robinson.
River Song: [winces] I hate you.
The Doctor: No, you don't.
River Song: We've told him all we can. We can't even tell him we've seen his future self. He's interacted with his own past. He could rip a hole in the universe.
Amy Pond: But he's done it before.
Rory Williams: And, in fairness, the universe did blow up.
The Doctor: Just popped out to get my special straw. It adds more fizz.
The Doctor: Fellows, the guns, really? I just walked into the highest security office in the United States and parked a big blue box on the rug. Do you think you can just shoot me?
River Song: They're Americans!
The Doctor: [puts his hands up] Don't shoot.
The Doctor: Now, then, Canton Everett Delaware III. That was his name, yeah? How many of those can there be? Well, three, I suppose.
The Doctor: You're lying.
Amy Pond: I'm not lying.
The Doctor: Swear to me. Swear to me, on something that matters.
Amy Pond: [she thinks for a moment] Fish fingers and custard.
The Doctor: My life in your hands, Amelia Pond.
President Richard Nixon: You were my second choice for this, Mr. Delaware.
Canton Delaware: That's okay. You were my second choice for president, Mr. Nixon.
The Doctor: Be careful!
River Song: Careful? Tried that once. Ever so dull.
The Doctor: Shout if you get into trouble.
River Song: Don't worry, I'm quite the screamer. Now there's a spoiler for you!
The Doctor: Oh, you bad, bad girl. What trouble have you got for me this time?
[River slaps him]
The Doctor: Okay. I'm assuming that's for something I haven't done yet.
River Song: Yes, it is.
The Doctor: Good. Looking forward to it.
River Song: This is cold. Even by your standards, this is cold.
The Doctor: Or "hello", as people used to say.
River Song: The Doctor's death doesn't frighten me, nor does my own. There's a far worse day coming for me.
Prison Guard: [as alarms go off] You better get down here, sir. She's doing it again. Dr. Song, sir. She's packing.
Canton Delaware: Mr President, that man walked in here with a big blue box and three of his friends, and that's the man he walked past. One of them is worth listening to. I say we give him five minutes and see if he delivers.
The Doctor: Thanks, Canton.
Canton Delaware: If he doesn't, I'll shoot him myself.
The Doctor: Not so thanks.
The Doctor: I'm going to need a SWAT team ready to mobilise, street-level maps covering all of Florida, a pot of coffee, twelve Jammie Dodgers and a fez.
Canton Delaware: Get him his maps.
River Song: When I first met the Doctor, a long, long time ago, he knew all about me. Think about that. Impressionable young girl and suddenly, this man just drops out of the sky. And he's clever and mad and wonderful, and knows every last thing about her. Imaging what that does to a girl.
Rory Williams: I don't really have to.
River Song: Trouble is it's all back-to-front. My past is his future. We're travelling in opposite directions. Every time we meet, I know him more, he knows me less. I live for the days when I see him, but I know that every time I do, he'll be one step further away. And the day is coming when I'll look into that man's eyes, my Doctor, and he won't have the faintest idea who I am. And I think it's going to kill me.
Canton Delaware: [pointing to the Doctor] Doctor who, exactly?
Amy Pond: That's classified.
Canton Delaware: Classified by whom?
Amy Pond: God knows
