Can you let me go to hell the way I want to?
If you love Jesus Lizard and are 100% proud of it, copy this and make it your signature!

I really liked Ellsworth and this few lines from him when we first meet him in episode one has always been one of my favorites. He had a very colorful way with words.
"Well here's to you, your majesty. I'll tell you what.I may a f#cked my life up flatter than hammered sh!t but I stand here before you today beholden to no human cckscker And workin' a payin' fvckin' gold claim. And not the U.S. government sayin' I'm tresspassin' or the savage fvckin' red man himself or any of these limber dick ccksckers passin' themselves off as prospectors had better try and stop me."

it's not really a line but a scene, in the first episode when Swearengen and some irish worker/thug are "negotiating" the irishman's cut for helping Al to con some other guy. Initially the irishman's cut was supposed to be quite high, like a couple of thousand but during the "negotiations" the cut kept falling and falling and in the end the irish guy got 20$ and a hand job from one of the whores (worth maybe 50c) lol!
It's been a while since i saw it last, but this scene gets me every time.
ps. i heard there are plans for a 4th season, anyone got any info on that?

Jane: "Every day takes figuring out all over again how to f-cking live."

So I love this show. For real, it has become one of my favorites. I've only watched Season 1 but I'm already looking forward to the rewatch.
But I was actually thinking this at one point and this thread has sort of confirmed itbut there really aren't many good LINES in Deadwood. Which is great. Most people are quoting whole scenes that require a setup (I say require, but more 'what makes it the best'). It's not about mind shattering one liners, it's about making you live in that situation in real time and feeling what it would be like at that moment in the Old American West.
I dunno, I'm CERTAINLY not saying there aren't any good one liners. Almost every line is a one liner. BUT, in comparison to other series who sort of 'strive' for those inspiring enlightening one liners, Deadwood trails behindwhich is I think one reason we all love it so much.
Anyone else?

Geez, it would take me a year to come up with a list of my favorite lines from Deadwood so I'll just give you the first quote that jumped in to my head: When George Hearst is instructing his employee to assault Merrick and describing what he looks like he says: "You will not mistake the newspaper man: he looks like a pauses to think big turtle"

Swidgen and wu talking is the funniest
"Swidgen kill sanfrancisco cock sucker"

SWEGEN !!!

Wild Bill: You know the sound of thunder, Mrs. Garret?
Alma Garret: Of course.
Wild Bill: Can you imagine that sound if I asked you to?
Alma Garret: Yes, I can, Mr. Hickok.
Wild Bill: Your husband and me had this talk, and I told him to head home to avoid a dark result. But I didn't say it in thunder. Ma'am, listen to the thunder.
Wolcott: Past hope. Past kindness or consideration. Past justice. Past satisfaction. Past warmth or cold or comfort. Past love. But past surprise? What an endlessly unfolding tedium life would then become.
Wild Bill: Sure you wanna quit playing, Jack? The game's always between you and getting called a beep dropped eye of yours looks like the hood on a beep to me, Jack. When you talk, your mouth looks like a beep moving.
Jack McCall: I ain't gonna get in no gun fight with you, Hickok.
Wild Bill: But you will run your beep mouth at me. And I will take it, to play poker.

I wanna know who cut the cheese. [nobody answers] Ill tell you this for openers: we are gonna set off an area on the balcony. [opens the door to the balcony] And God help whoever doesnt use it, because the next stink I have to smell in this office, and whoever doesnt admit to it is going out the window, into the muck, onto their beep heads, and well see how they like farting from that position, okay?

Yes, my first time watching just started the second season and Calamity Jane steals every scene she's in, but that quote about picking out a gown etc was one that stuck out and made me laugh. I also like when she arrived at docs earlier in the same episode attached to her horse and explained to him that it was something that she had made herself to stop herself falling off when she was blind drunk.

My two favorites are never mentioned. I don't know how
Jane : Aint it always a trial picking out the gown that best conceals you pissed yourself (to Johnny when he explains Al is getting dressed and will be a moment).
Utter : How much they pay you to hold that building up (to Jane as she drunkenly leans head forward into a buildings wall)

That scene with Wu
explaining
to Al about the two cck-sckers who stole his dope always worth a second look. Just hysterical.

"San Francisco corksoaker!"
So many fantastic lines of dialogue. Tell me something pretty, Milch. We need the Deadwood movie to happen.
"The heat has a taste. It tastes like a flame. You drink up the flame as it burns your flesh away."

I'm revisiting and have just started on season 2. there are so many great lines, but one that go me today was when Al opens a letter in front of Dan and Silas, and immediately reaches for his magnifying glass "Yes, it has descended to this." (I feel his pain)

"Hmm. When I say, "Go f-ck yourself, Sheriff," will you put that down to drunkenness or a high estimate of your athleticism?" (George Hearst)

I'm never anyone's first pick for appreciating fancy prose and yet the writing in "Deadwood" stands out. It's head and shoulders above the writing in any series I've watched, there's no mistaking something this exceptional. The writers respected the viewer's intelligence enough to go all out with the script and give it their best. The reason I appreciate it so much is, it's not just fancy for the sake of being fancy - the intricacy, intelligence and (top rate) humor never felt forced.

The interesting thing about that line is that "can be combative" was actually not a line but a dialogue direction in the script for how to say the previous line McShane accidentally took it as dialogue and it ended up working out well!

"Welcome to f@cking Deadwood!"
But you have to add the, "Can be combative"!
That's my favorite line. I also love Al's follow up later, "Cow-eyed kid looking from that coachthat's what f#ckin' unmanned me". What a statement about Al..

Too many good ones, but to go with a single line rather than bit of dialogue:
Some goddamn time, a man's due to stop arguing with hisself, feeling twice the goddamn fool he knows he is because he can't be something he tries to be every goddamn day without once getting to dinnertime and not ******* it up. I don't want to fight it no more. Understand me, Charlie? And I don't want you pissing in my ear about it. Can you let me go to hell the way I want to?

"Welcome to f@cking Deadwood!" - The look on Al's face while he's pointing the knife at William is amazing.
Too many else to mention.
No f@cking sh`t lady does it sound like I'm ordering a pizza!

"So including last night, thats three fing damage incidents that didnt kill you. Pain or damage dont end the world, or despair, or fin beatings. The world ends when youre dead. Until then, you got more punishment in store. Stand it like a man and give some back"
-Al to Merrick
"It rubs the lotion on its skin or else it gets the hose again."

Ding ding ding!!!! We have a winner!

Al watching Jewel walk up the stairs near the end of S3.
"Every step is a Fing adventure" I laughed pretty hard at that.
