Detective Dolly: So what's the symbology there?
Paul Smecker: Symbology? Now that Duffy has relinquished his "King Bonehead" crown, I see we have an heir to the throne! I'm sure the word you were looking for was "symbolism." What is the ssss-himbolism there?
[after Smecker gets a phone call in bed with his gay lover and slaps him]
Paul Smecker: What are you doing?
Hojo: I just wanted to cuddle.
Paul Smecker: Cuddle? What a fag.
Connor: Destroy all that which is evil.
Murphy: So that which is good may flourish.
[after Rocco accidentally turns a cat into a splatter on the wall]
Murphy: I can't believe that just fucking happened!
Rocco: Is it dead?
Ivan Checkov: I am Ivan Checkov, and you will be closing now.
Murphy: Checkov? Well, this here's McCoy. We find a Spock, we got us an away team.
Paul Smecker: [Agent Smecker walks up to the first crime scene, where Chekov and his partner lay dead] Brilliant. So now we got a huge guy theory, and a serial crusher theory. Top notch. What's your name?
Detective Greenly: Detective Greenly. Who the fuck are you?
Paul Smecker: [opens his coat and shows his FBI credentials] That's who the fuck I am.
[after Smecker proves the Boston detectives wrong]
Paul Smecker: We'll start the ass-kissing with you.
Paul Smecker: Oh, isn't that beautiful? All the lowlifes in quiet city Boston start dropping dead and *you* think it's unrelated! Greenly, the day I want the Boston Police to do my thinking for me, I will have a fucking tag on my toe!
Yakavetta: He's happy now, just killing us one by one. And worse, he's good at it.
[Yakavetta wants to call in Il Duce]
Augustus DiStephano: Your father and I used him three times in twenty years, only when things got totally fucked. Whenever we needed one of our own bumped off, we called this guy in. He had a thing for clipping wiseguys, but only one rule: No women, no kids. Believe me, kid, you don't want this guy unless you are one hundred percent sure you need him. He's a fucking monster.
[after Rocco shoots three men in a coffee shop]
Murphy: Liberating, isn't it?
Connor: Let's fuckin' go!
Rocco: You know, it is a bit.
Doc: You know what they say: People in glass houses sink sh-sh-ships.
Rocco: Doc, I gotta buy you, like, a proverb book or something. This mix'n'match shit's gotta go.
Doc: What?
Connor: A penny saved is worth two in the bush, isn't it?
Murphy: And don't cross the road if you can't get out of the kitchen.
[the two brothers are in an airshaft and getting a bit uncomfortable]
Murphy: Where the fuck are you going?
Connor: Shhh. I fucking hearin' some shit out here.
Murphy: Ahh, fuck you! I'm sweatin' my ass off draggin' your fuckin' rope around. Must weigh thirty pounds.
Connor: Shhh. We are doing some serious shit here, now get a fucking hold of yourself!
Murphy: Oh, *fuck you*! I'm not the rope-totin' Charlie Bronson wannabe that's getting us fucking lost!
Connor: Would you fucking shut it?
[taps him on the head with his flash light, and both brothers start fighting in the air vent until it gives way]
Connor: You mother- Jesus fucking Christ!
Murphy: Oh, shit!
[the vents give way]
[after Rocco fondles an unconscious stripper's breast]
Connor: What the fuck are you doing?
Rocco: ...I'll tip her.
Yakavetta: The 90's are killing me. I shouldn't have done that. You're not supposed to tell a guy you're gonna kill him no more. I got to tiptoe through the tulips with these assholes. Taking all the fun out of the job.
Il Duce: Never shall innocent blood be shed, yet the blood of the wicked shall flow like a river. The Three shall spread their blackened wings and be the vengeful striking hammer of God.
