Mac: What do you got for me, Sid?
Sid: If I had a nickel for every time I heard that question.

Mac: We know the science doesn't lie and people do.
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?
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.
Sid: I'm afraid I've spoiled everyone around here over the years. The age-old tradition of the investigator being present at autopsy is to answer questions that might assist the medical examiner, moi, in determining the cause and mode of death, not the other way around.
Mac: Well, that's what the book says, but I don't think they knew about Sid Hammerback when they wrote it. You always have more answers than questions, that's why you're the best.
Sid: Flattery will get you everywhere.
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.
Hawkes: The note paper I found on the vestibule floor is very promising. It took me a while to figure it out, but it's a New York State inmate I.D. number.
Jo: So what's your theory? That the killer jotted down his inmate number and left it behind at the scene of the murder?
Hawkes: Wow, it is a tough crowd today.
Lindsay: So what are the chances that Parole's gonna issue a warrant?
Hawkes: Pretty promising (hands her the warrant) Here is your ticket to the dance. Flack is your date.
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.
Mac: (after Christine pulls him into a corner and kisses him at the lab) What was that for?
Christine Whitney: 'Cause I felt like it. 'Cause you made me feel like it. And letting me into your world the way you have has just changed my life. I can't stop smiling. I can't stop thinking about you.
Mac: For a long time, this place and those guys have been my whole world. They've helped me through some tough times. Now I have you.

(exhales) Oh, son of a bitch. (to suspect) You run track or something? You on the Olympic team?
(out of breath) This is fun...this is funny to you? You realize you were in an automobile, right? You were not running 60 miles an hour.
Yeah, you want to ride back to the precinct or you walking?
(panting) Ride please.
Get in. Come on.
(sighs) They're so fast.
Come on, old man.
S9 E1Reignited
Don't look so smug. It ain't over yet.
Ah, let's see, osso bucco in a nice red wine sauce, porcini mushrooms...
And you wonder why the public likes us better. You guys are so cocky.
Oh, come on, Curtis. Your boys have won the last five. I'm tired of buying you dinner.
Hey, get your head in the game, kid. You're better than that.
Are you kidding me? Who just got nailed in the corner over there, all right? Get the puck along the boards!
Just keep your skates up against the post. You learn that in peewee league.
Hey, hey, hey, shut up, the two of you. We are not losing this game. We got two minutes left. Danny, I need you strong on the forecheck. Adam, nothing gets past you. Focus, baby. Focus. Let's go, boys.

Hey, Flack, that last goal was for your mother. This next one's for your sister.
My sister died six months ago, jackass.
HPHockey player
No. Bro, I didn't know.
She's not dead, you idiot. Mention my family again, I'll punch you in the mouth.
