(after Dr. Sid Hammerback determines that the murder weapon is a foot)
Danny Messer: Right foot of a woman?
Dr. Sid Hammerback (surprised): Right... It is correct. And female would explain the traces of red nail polish I found in the wound.
Danny Messer: So our murder is a one-legged barefoot woman, who´s got serious kung-fu skills.

(talking to the secretary of a murdered suspect)
Mac Taylor: What was he doing during these four hours?
Secretary: I don´t know. Once a month he tells me to block out four or five hours like that, I never ask. I figured he´s seeing a shrink or something?
Mac Taylor (watching the secretary carefully): Did he need a shrink?
Secretary: Do I have to answer that? I mean, I really don't like talking badly about dead people.

Abel Bloom: We're Jewish.
Dr. Sheldon Hawkes: Orthodox?
Abel Bloom: Traditional. That's... that's how Hannah would describe us. You do it because you believe it, not because you fear it. That's what she always said.

Adam Ross: [to Mac] You were born to do this work. [Mac laughs]

Adam Ross: Check this out. [He puts a slide under the microscope] Alright, look, look. It's a piece of the moon. A moon rock. Yeah, this rock is, is from the moon.
Detective Danny Messer: From the moon?
Adam Ross: Outer space.
Detective Danny Messer: Get outta here. Wow. How did a piece of the moon end up in the alley?
Adam Ross: I-I don't know. This stuff is illegal to have and somebody went through a lot of trouble to get it. I mean I've seen this stuff listed on eBay before, you know, and most of it isn't real, but if it is short of going to the moon they would have had to steal from NASA.
Detective Danny Messer: Something happened in that alley and I don't think it had anything to do with what happened in the warehouse.
.

Adam Ross: Hey guys.
Detective Stella Bonasera: Adam.
Adam Ross: Hey Danny, you remember that rust stuff you found in the alley?
Detective Danny Messer: Rust stuff? Rust stuff? You respect the time it took me to collect that, at least call it "trace."
Adam Ross: Okay. Contained traces of molasses and non-human blood. Bear blood to be exact.
Detective Stella Bonasera: What?
Adam Ross: North American Grizzly Bear. But, but there's more. The blood on this rock is a match to Cyrus Menlo, but it's also a match to the blood found on these leaves.
Detective Stella Bonasera: Both human blood, right?
Adam Ross: Right. [Holds the two leaves up]But you put them together like this and shazam.
Detective Danny Messer: You got one leaf - with a hole in the middle of it.
Adam Ross: A hole probably made from a spike or something with a jagged edge. Right, huh, you see where I'm going here?
Detective Stella Bonasera: Bear blood, molasses, leaves with human blood on them, a spike and a jagged edge, you're talking bear traps.
Adam Ross: Yes, you win the washer and dryer.
Detective Danny Messer: Whoa, whoa, whoa, help me out here. You're telling me Cyrus Menlo was caught in a bear trap?
Adam Ross: Yeah.
Detective Danny Messer: You're crazy.
Adam Ross: It's the only conclusion we can arrive at with this evidence.
Detective Danny Messer: So Tanaka sets the bear trap, leads Cyrus Menlo down the alley, Tanaka goes into the warehouse...
Adam Ross: - Bang bang, Tanaka gets shot. Cyrus walks out, steps in the trap while Tanaka bleeds to death inside the warehouse. Moral of the story, alright: stick with bowling. What up?
[He and Danny fist bump] .

Adam Ross: Strange case, you know. Bar nuts, shark tooth, tropical fish.
Detective Mac Taylor: Beta Splendon. Or Siamese Fighting Fish, to be exact. The brilliant colors are exclusive to males. Males in the same tank will kill each other.
Adam Ross: Ironic.
Detective Mac Taylor: No. Wild Wild Wet.
Adam Ross: [laughs] Whoa. That's a very hip, very salacious Manhattan club. It just kind of popped in your head like that?
Detective Mac Taylor: And your point?
Adam Ross: [flustered] Well... well I just - just didn't think that you would just...
Detective Mac Taylor: The bar's over on Broadway near Chelsea University, Fighting Fish on every table. It's a short train ride from where Randy Williams was found.
Adam Ross: [impressed] Ah you're the man, you can hang anywhere you want, huh?
Detective Mac Taylor: I was at the scene of a crime, Adam. The bouncers went a little overboard, ended up killing some kid from Staten Island. Shrimp cocktail is fantastic. Get me something more on that tooth.
[Mac leaves]

Adam Ross: That glass that Dr. Hawkes pulled from our John Doe... it tested positive for Krypton.
Det. Mac Taylor: Krypton?
Adam Ross: Kryptonite was Superman's only weakness.
Det. Stella Bonasera: Well, that explains everything.

Adam Ross: The penal code is his personal to-do list. You name a section and he's violated it.

Adam Ross: Turns out our suspect is not as spooky as she wants us to believe. I mean, come on, if this was a real ectoplasm, what's it doing shopping? Unless it's, like, the spirit of Imelda Marcos, but I don't even think she's dead.

Adam Ross: [Don Flack is about to shoot two masked men whose hands are duct taped to a gun. He doesn't realize that they are cops] No no no! Don't shoot them! Don't, they're cops, see... they're cops... do you see them?
Season 4

Adam Ross: [nods] I like shrimp.

Adam Ross: [Rubbing his chest] Ow.

Adam Ross: [Watching survelliance of the suspect] I can tell she's got a bully in her life. Check that out. Look how she flinched when a customer raised his hand.
Detective Danny Messer: Could be too much coffee.
Detective Stella Bonasera: Or a sign of abuse, and withdrawal like that is a classic symptom of PTSD.
Detective Danny Messer: [to Adam] How'd you know that?
Adam Ross: Huh, uh, uh, my, uh, my dad was a bully.

Adam Ross [to Hawkes]: Hey, what do you know about Fishzilla?
Sheldon Hawkes: Sounds like a bad name for a monster movie.
Adam Ross: Close... it's the nickname of that weird little thing I found at the bottom of the mezcal bottle. Yeah, its real name is snakehead fish, all right, and it's illegal in all 50 States.
Sheldon Hawkes: Then it couldn't have been that easy to get. How did it end up at our crime scene?
Adam Ross: Uh, I don't know, maybe it was left as a message. You know, these things are pretty vicious. They eat everything, even their own kind.
Sheldon Hawkes: The message could be in the name. Snakehead... reference to the Mambas?
Adam Ross: I'm trying to track down where you can buy these things and then maybe I can figure out who purchased it.
Sheldon Hawkes: How are you going to track it down if it's illegal and off the books?
Adam Ross: I... I know a guy that knows a guy that... knows a guy that knows another guy.
