(Soon after the Word Trade Center collapsed, Flack and Danny stumble upon each other)
Don Flack: Hey, buddy, you can't go down there.
Danny Messer: It's okay, I'm on the job.
Don Flack: What's your name?
Danny Messer: Messer. Danny Messer.
Don Flack: Listen to me, Messer. You don't need to go down...
Danny Messer: No, I got to get down there and help!
Don Flack: Listen to me, Messer. They're all gone!
Danny Messer: I want to go help these people!
Don Flack: They're all gone.

(Stella is found passed out on her apartment floor)
Mac: Stella. Stella. Stella!
Stella Bonasera: (wakes up)...Where's Frankie?

(Stella pleads with her ex-boyfriend, who has her captive in her apartment)
Stella: You caught me off balance. I do love you, Frankie, that statue you made for me was beautiful. I meant to answer your messages, really I did...
Frankie: (quietly) But you didn't. (Stella's face shows her dismay) You didn't answer my messages. You didn't call. That tape was a testament to our love and you spurned it. You don't love me. You're going to pay for not loving me.

(To Det. Angell, who is bent over a half-naked body)
Danny: We interrupting something, Detective?

(to the bad guy tied to the chair)
Mac: It's simple. If you find someway to get out of that tape, or someone tries to save you, they trip these lasers which set off the pipe bomb rigged to that hydrogen tank over there. That's enough explosive to kill you, and make the cleaning crew very unhappy.

(Victim is covered in money)
Danny Messer: I think we can rule out robbery...

(while doing a reconstruction of the shooting w/ Danny behind her)
Lindsay: Definitely, could have gone through the love handles. (smiles and pinches his stomach)
Danny: That's too low, wise-ass.

(while working the late-late shift in the cemetery)
Grave Digger #1: Smallpox, Yellow Fever, influenza. She had the Bubonic Plague.
Grave Digger #2: (digging) What are you talking about, Pops?
Grave Digger #1: Long ago when several coffins were excavated and scratches were found inside, our ancestors, they realized they'd been burying (snickering) folks before their time. No kiddin'. Back then, when the plagues hit, guys like you and me, we couldn't dig fast enough.
Grave Digger #2: (not believing) Come on!
Grave Digger #1: Saved by the bell doesn't mean what you think. Morticians would tie a string to the hand of the dead person and take the other end of the string and tie it to a bell, aboveground. And immediately after the, uh, burial, a person from the mortuary would be assigned the task to sit by the new gravesite and listen for the bell to ring. (laughs) That was called the graveyard shift.

[A piece of paper was retrieved from the dead teenager on which only three letters could be read]
Stella: Playing hangman?
Mac: Actually, yes. But I've run out of letters.

[A skeleton has been found on a tour bus in Times Square]
Stella Bonasera: How long is this tour? [Mac looks at her disbelievingly] That's funny.

[about id'ing their vic]
Hawkes: I'd say a homeless guy probably living where we found him, in the park.
Stella: Park Avenue, maybe. I've got a really nice pair of pants, a tailor-made shirt, fancy watch, traces of paint and lipstick on the shirt, I'd say he's a very wealthy guy.
Hawkes: Well, he must have found the clothes. The shoes never lie.
Stella: Yeah well, this little watch here is worth four or five grand, quite a find for a homeless guy.
Hawkes: Yeah.
Stella: Let me check missing persons. Someone notices when a guy with money doesn't come home.
Hawkes: The way I see it, homeless people are missing people.

[About the burn victim]
Angie: Buyer beware. Kandy was a gold digger. I just wanted her next lover to know all the facts. I gave her everything she wanted. And she burned me.
Mac: And someone did the same to her.

[About the burn victim]
Hawkes: Tattoo on the inner thigh, means eyes only, means our vic had a lover.
Marty: Lovers' spat? Things got a little heated?
Hawkes: Literally.

[Adam is doing something in the computer and starts laughing]
[Danny notices he is playing with the aging software using Lindsay's face]
Danny Messer: [Laughing] Hey, come on, that's not right, don't do that, stop.
Lindsay Monroe: What?
Danny Messer: He's just messing with the age progression software.
[Lindsay walks across table to see]

[Adam Lindsay and Danny in the garage, putting together a burnt race car]
Lindsay: Somebody did a bad thing to a good fencooler.
Adam: You a racing fan?
Lindsay: Anything that rips it up 200 miles an hour, you gotta respect.
Danny: Haha...that's my girl. You grow up in Montana and you love race cars.
Linds: Maybe stop cars, but open wheel...that's a whole different thing.
Adam: I know what you mean. Paddle-shift versus stick, front rear wings and you have the whole LCD steering wheel that you basically need an engineering degree to operate.
Lindsay: You race?
Adam: Playstation.
[Lindsay laughs]
Adam: Those games are very realistic.
Danny: All right, Speed Racer, calm down.
