Walter White: Who are you talking to right now? Who is it you think you see? Do you know how much I make a year? I mean, even if I told you, you wouldn't believe it. Do you know what would happen if I suddenly decided to stop going in to work? A business big enough that it could be listed on the NASDAQ goes belly-up, disappears. It ceases to exist without me. No. You clearly don't know who you're talking to, so let me clue you in. I am not in danger, Skyler. I am the danger. A guy opens his door and gets shot, and you think that of me? No. I am the one who knocks.
