[They just arrested a young woman at the sushi bar]
Danny: Here we are looking for the murderer at the table...
Stella: And here, the murderer is the table.

[They lift out what they thought was a trunk from the sand]
Stella: That's not a trunk. It's a box!
Mac: It's not a box. It's a coffin.

[To a man in a blue party]
Lindsay Monroe: NYPD as in Blue, let's see what you make of that.

[to Darius in holding cell]
Mac: Me? I don't pity you, Darius. There's lots of people with worse stories than yours and they never hurt anyone. You killed twelve people in two states over the last seventy-two hours, and you want me to feel sorry for you because your daddy didn't kiss you when you were a baby? You asked for my help. I did help you. You're where you belong. [pauses] Rot in hell, you son of a bitch.

[To Razzi Suicide who is acting childishly during interrogation]
Lindsay Monroe: Do I need to give you a time-out?

[to Sonny Sassone, a member of the self-proclaimed "next generation" of the Mafia]
Mac: Let me tell you something about the Mob. Back in their heyday, these old timers, they dealt in death and violence because of one thing: business. Not sport. They were smart. You punks are idiots.

[Watching Mac reading to a little child in his office]
Lindsay: Under the heading, "Things I Never Thought I'd See."

Adam: (playing an Xbox video game) Hey, Mac. Listen, why don't you pull up a chair and challenge the champ, okay? Now, look. I just want to warn you, this is not like the old-school games. Grab this. See these little buttons here? Press those. It's not like in the olden days, with the black and white screen and the little ball, or Ms. Pac-Man...

Adam: If this is Hell's Kitchen in 1970, as it moves into 1975, '80, '85 and so on, you'll see the change. Anything that turns blue has been bought up, remodeled, torn down or rebuilt. Corporate America moves in.
Mac: And the older generations, like Byrne, who were born and raised there, are driven out because they can't afford the soaring costs.

Alicia Woods: I just can't believe that he's dead. You know, he was such a special man. Everybody loved him.
Flack: Not everybody.

Christine Whitney (to Mac): Hey, I'm having a crisis of conviction in the middle of a toy store.
Mac: Okay.
Christine Whitney: My head says pick the developmentally-stimulating blocks made from organic recycled wood, but my heart says princess doll.
Mac: Well, I'm sure whatever you pick, Lucy's gonna love.
Christine Whitney: Oh, you have obviously never disappointed a 3-year-old.
Mac: I always say, go with your gut.
Christine Whitney: Oh... or we could go with ponies!
Mac: Should I send a squad car to rescue you?
Christine Whitney: Well, what is everybody else bringing?
Mac: Wait a minute. This isn't about Lucy, is it?
Christine Whitney: Of course not. This is about meeting your friends for the first time and that's a lot of pressure.
Mac: If they see in you even a fraction of what I see... you'll be a hit.
Christine Whitney: You're a sweet man, Mac Taylor. Go solve crime.

Christine Whitney: Mac Taylor, you're an idiot.
Mac: Why is that, exactly?
Christine Whitney: 'Cause I'm a catch, and you're gonna lose me.
Mac: I should have called, I know. Besides work and the fact that I'm not very good at this...
Christine Whitney: Hey, it's not about the phone call. If you're not... ready for something or, um... work's too busy or your life's complicated or you're scared, I get it (Laughs) I mean, I'm scared, too. Look, um, when your brother dies in the line of duty, the last guy you want to date is a cop. But I'm here and... we kissed, and I guess I just want to know if it felt right to you, too.
Mac: It did.
Christine Whitney: (Laughs) Good.
Mac: So, how about I make it up to you. We'll go out to dinner tonight. I know this amazing restaurant with this incredible chef.
Christine Whitney: Well, why don't you just come by the... (Laughs) Oh! Cute. You mean me.

Clyde Duvall: There's two kind of people in this building. People like them...
Danny: Yeah, scumbags.
Clyde Duvall: And people like me and Alicia. We work hard, we mind our business, and we try not to get caught in the crossfire.

Elaine Moore: Look, I know you must think I'm a horrible person for cheating on my husband. I loved Kelvin. Just not the way everyone wanted me to.
Lindsay: I don't think you're a horrible person. I just think it's sad that you didn't realize that the greatest gift you had walking into that building yesterday was standing right next to you.

Flack: (banging on the door) Police! Open up!
Willis Frazier: You got a warrant?
Flack: We can get one.
Willis Frazier: Or you could ask nice.
Flack: May we come in?
