CSI: NY Season 4 Episode 4

Mac: Probability... there's usually choices to make. Maybe Kevin didn't have one.

Stella: Turns out it's an experimental sexual enhancement drug, only available in clinical trials.
Danny: Don't look at me, I don't need it.
Stella: You're too old anyway, it's currently being tested on students at Chelsea University's health center.
Danny: Argh, it's like throwing gas on a raging hormonal fire.

Danny: So far we're not hearing COD.
Sid: I see you're not much for foreplay, very well...

Mac: There's a fine line between genius and insanity.

Flack: (looking at the time machine) The thing looks like an electric chair with mood lighting.

Danny: (To kid) You know, for a smart kid, you're a real bonehead. Let's go.

(After their new victim is unmasked and is revealed as Kevin Murray)
Mac: (Looks at his watch) I'll be damned, he's right on schedule.

Hawkes: Why didn't you report this when it happened?
Dean: Because I finally decided to wash my hands off Martin. I could see already there'd be nothing but trouble in his future.
Hawkes: Hard to know that without traveling through time.

Flack: I dunno, if I could go anywhere back in time, I'd probably go back to my folks' place in Queens for my mom's corn beef Wednesdays. Yeah, I'd endure every one of my brothers' insults for one more taste of that paradise.

Hawkes: (holds up swab with blood on it) Someone came knocking a little too hard, I can tell you that much.

Sid: Well, I don't know how she was capable of drawing on her own buttocks.
Danny: I knew a kid in the Bronx who could blow out a candle with his own--
Stella: (hurriedly interrupts him) What about stomach content?

Mac: (Sees the glass on the floor with blood) Looks like this is where his time finally ran out.

Hawkes: A hand held GPS unit.
Adam: Only this time it was hand mounted (Sheldon smiles).

(After Stella explains the origins of her parachute gift.)
Mac: Original and daring.
Stella: And a bit too aggressive for me.

Witness: It was a typical night time crowd. Dumb kids, blue hairs and blow hards.

Mac: Again, unless you have some information to share to shed some light on our victim, we'll see what else we can do for you.
Kevin: (Stands) How 'bout guaranteeing I'm still alive in 24 hours?
Mac: (Wry grin Ah, nobody knows what the future holds. C'mon, bye bye. Thank you. (Shows Kevin out the interrogation door).

Kevin: No, I've never seen this guy before.
Flack: You sure 'bout that?
Kevin: Yeah, I'm sure, why?
Flack: Because he just confessed to your murder.

Hawkes: (excitedly) In theory, if you built a machine that could travel the speed of light away from here, then slowed down, turned around and flew home just as fast, when you got back, a trip that might have lasted just seconds for you, could've been weeks for everybody else.
Flack: Kinda like your explanation.

Flack: (to Hawkes, about the vicitm) Have any pictures of him in a straightjacket?

Mac: (to Stella, about romance) You and I are alike in a lot of ways, we both do everything we can to avoid this sort of thing. Sometimes, you just gotta take the plunge.

(While they are arresting Kelsey).
Kelsey: Well, at least she went with a smile on her face.
Stella: No, and I can promise you this: you won't either.

Danny: Fan-TAS-tic. We got horny college kids and horny mammoths.

Sid: In this case, the cause of death was an aortic aneurysm due to extrem sexual excitement...
Stella: Death by orgasm?

(After Stella opens a box with a parachute in it).
Mac: There are safer ways to avoid the traffic.
Stella: Oh, traffic I can handle. Men are another story.
