Ella McBride: You always so confident and sure of everything?
Detective Mac Taylor: 99.2% of the time.

Flack: (about the pet leopard) Big house cat.
Terrence: You could say she puts this club on the map.
Flack: Not really into cats myself.
Terrence: Lemme guess, you're more K-9?
Danny: You're smarter than you look.

Flack: (sneezes as he and Danny enters a club) Either I'm allergic to half naked women, or there's a cat in here.
Detective Danny Messer: [pointing out a different scantily clad lady walking through the club with a leopard on a leash] There's a cat in here.

Flack: Did you get a description of the bird?
Stella: [sarcastic] Yes Flack; It was black, had a beak, oh! And it flew with a limp.
Flack: [amused] I'm just trying to do my job.
Stella: I mean what are the odds. I was just standing there, and out of nowhere: ploc!
Flack: I am gonna get a cup of coffee. You want one?
Stella: No, Thank you [amused].

Flack: Homeland Security is talking to all the women passengers again. Let me ask you this, if one of them had sex with our vic, why kill a man over this?
Mac: Some black widow spiders are known for eating the male after they mate.
Flack: Well at least they go out with a smile on their face.

Flack: I wish I knew what to say.
Cliff Angell: You can tell me she didn't die protecting that scumbag murderer.
Flack: No, I can't. But I can tell you that she did the job the best, she could no matter what the assignment and, uh... that's who she was.
Cliff Angell: She was too damn brave for her own good.
Flack: From what I hear, she took after her old man.
Season 6

Flack: Listen to me, somebody in your little entourage knows this guy, okay? We made a deal, you're a confidential informant and this little pow-wow that we're having is pay up time.
Terrence Davis: I'm aware of the deal we made, sorry I can't keep coming up with all the small change though, I'm beginning to smell like pork.

Flack: Somebody brought a group of underage girls into your club, drugged them, forced them to have sex with I dunno how many men, I dunno how many times!
Willy Burton: It didn't happen in my establishment. I don't provide women for sexual services! And I definitely don't treat them that way! You're disrespecting me, and you're disrespecting my mother cause she taught me better than that.
Flack: My apologies to your mother.

Flack: When did you start hiding behind Buddha?
Lhamo Vadhana: Oh, my transition occurred when I stopped hiding.
Flack: Great. Then you won't mind telling us what you know about these two people.
Lhamo Vadhana: I'm not familiar with these individuals.
Flack: No? 'Cause we're familiar with your tendency to go nuclear. And since these poor folks died of radiation poisoning, and one of them had your address in his pocket.

Hannah Schnitzler: Perhaps there's someone you want to honor?
Mac: My father
(from video-mail Mac receives from Mr. Lesnick)

Hawkes: (cuts in on Flack as he questions Pino) Come on. What are you doing? The man just lost his wife.
Flack: He's lying about something.
Hawkes: He's scared, confused.
Flack: And he's your friend, Sheldon, so I understand why you're hearing something different.
Hawkes: There's no doubt Marty's made some mistakes. But I know he loved his wife. He couldn't have killed her.
Flack: Okay, then prove it

Hawkes: Honestly, I think what Danny's doing is selfish.
Lindsay: Really? Well, I see it as committed.
Hawkes: Seems to me he has a lot of other things to commit to right now, not to mention it's irresponsible to risk suspension when you are expecting a baby.
Lindsay: Hawkes! You transferred over from the ME's office, which means you are not a sworn NYPD. There was no decision for you to make. You can not say for sure what would you do.
Hawkes: Yes, I can. If I earned a distinction of being a detective, I'd be here whether or not the city can afford to pay me.

Hawkes: How you doing?
Sid: Let's just say I know how a microwaved burrito feels. But I should also say thank you. I owe a great deal of my recovery to you.
Hawkes: Ah, come on, that was nothing. You would have done the same for me.
Sid: As a matter of fact, I would.

Hawkes: So what do you want me to do? Just ignore the fact that Colin's sweat is on our murdered victim's clothes?
Mac: The reason we follow FBI DNA protocol is to ensure an unquestionable conviction.
Hawkes: So we sit in here waiting for that perfect scientific connection while Colin could be out there raping and killing another innocent victim? I don't know about you, Mac but I can't live with that.

Hawkes: You got plenty of time on this name search. I mean, the kid's not even here yet. My mom and dad waited six weeks after I was born to name me.
Danny: Oh, they waited six weeks to name you Sheldon?
Hawkes: Yeah. What's wrong with that?
Danny: No, that's cool. That's a great name. I'll see you later, Sheldon.
