Nick Fury: Sir! I'm going to have to ask you to exit the donut!
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.
Ivan Vanko: If you could make God bleed, people will cease to believe in Him. There will be blood in the water, and the sharks will come. All I have to do is sit here and watch, as the world will consume you.
Ivan Vanko: You come from a family of thieves and butchers. And now, like all guilty men, you try to rewrite your own history. And you forget all the lives the Stark family has destroyed.
Tony Stark: I am Iron Man. The suit and I are one.
Justin Hammer: This is a kinetic-kill, side-winder vehicle with a secondary cyclotrimethylenetrinitramine RDX burst. It's capable of busting a bunker under the bunker you just busted. If it were any smarter, it'd write a book, a book that would make Ulysses look like it was written in crayon. It would read it to you.
Tony Stark: I'm busy, what do you want?
Phil Coulson: Nothing. Goodbye. I've been reassigned. Director Fury wants me in New Mexico.
Tony Stark: Fantastic. Land of Enchantment.
Phil Coulson: So I'm told.
Tony Stark: Secret stuff.
Phil Coulson: Something like that. Good luck. We need you.
Tony Stark: Yeah. More than you know.
Phil Coulson: Not that much.
Pepper Potts: I only have 8,011 things to talk to you about.
Justin Hammer: I wanna make Iron Man look like an antique.
Justin Hammer: What you did to Tony Stark on that racetrack... WOW!
Answer: He wanted to do something nice for her, but since he is a pretty self-absorbed, shallow multi-billionaire, he forgot about her allergy. He remembered that there was SOMETHING about her and strawberries, but misremembered and thought it meant she really liked them. He makes a simple human mistake, not out of meanness or spite, but because he honestly does not remember.
