Breaking Bad - Season 4

Jesse: "Tell this asshole if he wants to learn how to make my product, he's got to do it my way, the right way."
Mexican Cook: "I speak English."
Jesse: "So you understand what asshole means. Now, go get me my phenylacetic acid, asshole."

"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!"

"Well, at least this time he didn't shit himself... guess that's progress."
[about Tio Salamanca]

Skyler: "What happened?"
Walter: "I won."

"I have lived under the threat of death for a year now. And because of that, I have made choices. Listen to me. I alone should suffer the consequences of those choices, no one else. And those consequences, they're coming. No more prolonging the inevitable."

Skyler: "There's got to be another way."
Walter: "There isn't. There was. But now there isn't."
[after Skyler burned their Money with Ted]

"You and I don't wear the same rose-coloured glasses where Johnny Fabulous is concerned."
[to Skyler about Ted]

"So what if this is like, math, or algebra? Now you add a plus douchebag to a minus douchebag, you get like, zero douchebags."
