Peter Highman: What? Fuck You!

[Pepper catches him in Iron Man suit.]
Virginia 'Pepper' Potts: What's going on here?
Tony Stark: Let's face it, this is not the worst thing you've ever caught me doing.
Tony Stark: No one's allowed to talk, is that it? You're not allowed to talk?
Driver: No, you intimidate them.
Tony Stark: Good God! You're a woman!
Yinsen: That doesn't look like a missile... What are you building, Stark?
Tony Stark: I'm working on something big.
Tony Stark: I feel like you're driving me to court martial. This is crazy. What did I do? I feel like you're gonna pull over and snuff me. What, you're not allowed to talk? Hey, Forest...
Jimmy: We can talk, sir.
Tony Stark: Oh, I see. So it's personal. All right.
Ramirez: You intimidate them, sir.
Tony Stark: Good god, you're a woman! I honestly couldn't have called that. I mean, I would apologize, but isn't that what we're going for here? I thought of you as a soldier first.
Ramirez: I'm an airman.
Tony Stark: Well you actually have excellent bone structure there. I'm having a hard time not looking at you now. Is that weird?
Tony Stark: Is it better to be feared or respected? I say, is it too much to ask for both?
Tony Stark: I never got to say goodbye to my father. There's questions I would've asked him. I would've asked him how he felt about what his company did, if he was conflicted, if he ever had doubts. Or maybe he was every inch of man we remember from the newsreels. I saw young Americans killed by the very weapons I created to defend them and protect them. And I saw that I had become part of a system that is comfortable with zero-accountability.
Press Reporter 1: Mr. Stark, what happened over there?
Tony Stark: I had my eyes opened. I came to realize that I had more to offer this world than just making things that blow up. And that is why, effective immediately, I am shutting down the weapons manufacturing division of Stark Industries.
Tony Stark: Why are you trying to hustle me out of here?
Virginia 'Pepper' Potts: Your flight was scheduled to leave an hour and a half ago.
Tony Stark: That's funny. I thought with it being my plane and all, that it would just wait for me to get there. I mean, doesn't it kind of defeat the purpose of having your own plane if it departs before you arrive?
Senator Stern: Our priority here is to have you turn over the Iron Man weapon to the American people.
Tony Stark: Well, you can forget it. We're safe. America is secure. You want my property - you can't have it! But I did you a big favor. I have successfully privatized world peace.
Tony Stark: I am Iron Man. The suit and I are one.
Tony Stark: Things are different now, I have to protect the one thing that I can't live without. That's you.
Tony Stark: I'm Tony Stark. I build neat stuff, got a great girl, occasionally save the world. So why can't I sleep?
Tony Stark: Dads leave. No need to be such a pussy about it.
Tony Stark: Jarvis, do me a favor, blow the Mark 42.
Tony Stark: Stop stopping.

Dr. John Watson: I've never complained! When have I ever complained about you practising the violin at three in the morning, or your mess, your general lack of hygiene, your experiments on my dog, or the fact that you steal my clothes?
Dr. John Watson: Holmes, does your depravity know no bounds?
Sherlock Holmes: No.
Irene Adler: Why are you always so suspicious?
Sherlock Holmes: Should I answer chronologically or alphabetically?

Sherlock Holmes: You have the grand gift of silence, Watson. It makes you quite invaluable as a companion.
Sherlock Holmes: Never theorize before you have data. Invariably, you end up twisting facts to suit theories, instead of theories to suit facts.

Sherlock Holmes: Data, data, data. I cannot make bricks without clay.
Inspector Lestrade: In another life you'd have made an excellent criminal.
Sherlock Holmes: And you an excellent policeman.
Dr. John Watson: It's happening. Whether you like it or not, 8:30, the Royale. Wear a jacket!
Sherlock Holmes: You wear a jacket.

Kirk Lazarus: An imbicile?
Tugg Speedman: Yeah!
Kirk Lazarus: Like the dumbest motherfucker that ever lived?
Tugg Speedman: ...when I was playing the character.

Kirk Lazarus: Suck my unit.
Kirk Lazarus: Cover me, limp dick fuck-ups!
