"Jesse, your actions have consequences that affect other people."

"Chemistry is the study of matter, but I prefer to see it as the study of change. It is growth...then decay...then transformation."

Jesse: Oh, well heil Hitler, bitch!
Jesse: I wanted to leave them on the counter! ...Bitch.
Jesse: YO! WHERE'S THE OTHER HALF, BITCH?
Jesse: This is my own private domicile and I will not be harassed... bitch!
Jesse: You're my free pass... bitch.
Jesse: So roll me further, bitch.
Jesse: Yo, Gatorade me, bitch!
Jesse: YEAH, BITCH! MAGNETS!

"So be on notice: We got new players in town. Now we don’t know who they are or where they came from, but they possess an extremely high skill set. Me personally, I think Albuquerque might just have a new kingpin."

Walt: So, what do you watch?
Jesse: I don't know, stuff.
Walt: Like what?
Jesse: I don't know. Ice Road Truckers.
Walt: Ice Road Truckers. What happens on that one?
Jesse: Guys drive on ice.

Skyler: You are in over your head.
Walt: Who are you talking to right now? Who is it you think you see? Do you know how much I make a year? Even if I told you, you wouldn't believe it. 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 are 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, you think that of me? No. I am the one who knocks!

Mike: Just because you shot Jesse James don’t make you Jesse James.
Walt: I’ve always thought of myself as more of a Doc Holiday.

"You know how they say it's been a pleasure... It hasn't."

Jesse: Are you in the meth business, or in the money business?

Heisenberg: Neither, I'm in the Empire business.

Walter: Now... say my name.

Declan: (pauses) ...you're Heisenberg.

Walter: You're goddamn right.
