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.
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.
