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 into 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 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!
Skyler White: What happened?
Walter White: I won. (00:47:50)
Chosen answer: I'm not sure how far you are into the show but he does eventually come up with a way to launder it (wont spoil it for you but rest assured, when he gets a lawyer the show gets much better!) and in the final season he also comes up with a way to give his children his money without the cops or the DA knowing it came from him.
