Pepper Potts: What is going on here?Tony Stark: Let's face it, this is not the worst thing you've caught me doing.Pepper Potts: Are those bullet holes?
Yinsen: That doesn't look like the Jericho missile.Tony Stark: That's because it is a miniaturized arc reactor. I've got a big one powering my factory at home.Yinsen: What will it generate?Tony Stark: If my math is right, and it always is, three gigajoules per second.Yinsen: That could run your heart for fifty lifetimes!Tony Stark: Yeah... or something big for fifteen minutes.
Pepper Potts: Don't ever, ever, ever, ask me to do anything like that, ever again!Tony Stark: I don't have anyone but you.
Tony Stark: What the hell did you do to me?Yinsen: What I did is to save your life. That is an electromagnet hooked up to a car battery. I removed as much shrapnel from your chest as I could, but there are still some pieces left. I've seen plenty of injuries like that. In my village we call those casualties "the walking dead" because they take about a week to reach your heart.
