Oh yeah, I'm kinda obsessed with this show. I've seen it three times already and I'm still regularly rewatching episodes. Every episode has so many unforgettable scenes and memorable quotes, I could never list them all. Still, here are some randomly chosen favorites (obvious SPOILER WARNING):
"Crazy Handful Of Nothin'" - Teaser scene and Walt & Tuco scene:
No matter what happens, no more bloodshed. No violence.
"Salud" - Jesse in the Mexican superlab, kicking serious cartel-chemist-ass:
I'm the guy your boss brought here to show you how it's done, and if this is how you run your lab, no wonder. You're lucky he hasn't fired your ass. Now, if you don't want that to happen, I suggest you stop whining like a little ***** and do what I say.
"Madrigal" - Jesse finding the fake ricin cigarette (such amazing acting from Aaron Paul)
"Buyout" - Teaser scene (imo the darkest minutes of BB ever) and Walt, Skyler & Jesse in a hilariously awkward dinner scene:
I eat a lot of frozen stuff. It's usually pretty bad. I mean, the pictures are always so awesome, you know? It's like, "Hell yeah, I'm stoked for this lasagna", and then you nuke it, and the cheese gets all scabby on top, and it's like - it's like you're eating a scab. I mean, seriously, what's that about? It's like, yo, whatever happened to truth in advertising? You know?
"Say My Name" - Teaser scene:
So it's grade school T-Ball versus the New York Yankees. Yours is just some tepid, off-brand, generic cola. What I'm making is classic Coke.
"Blood Money" - Walt & Hank garage showdown scene:
It was you! All along, it was you! You son of a *****. You drove into traffic to keep me from that laundry. That call I got telling me Marie was in the hospital, that wasn't Pinkman. You had my cell number. You killed ten witnesses to save your sorry ass. You bombed a nursing home. Heisenberg. Heisenberg! You lying, two-faced sack of honeysuckle. I swear to Christ, I will put you under the jail.
Honorable mention: All the montages of this show. They're all brilliantly shot and edited, not to mention the excellent music choices.
