Numb3rs Season 5 Episode 11

Colby: Ok, hand, please?
Nikki: (takes out phone and takes a picture) Something to remember when that next funny remark comes in your head.

(Charlie asks if Alan would like to join CalSci's Thinktank group)
Alan: You know, I still remember the time when you asked me for, um, an estimate on the remainder term for a Taylor expansion of the hyperbolic cosine.
Amita: That's a very specific memory, Alan.
Alan: One never forgets the moments when one realizes he has nothing left to teach his seven year-old son about math.
Chalie: Yeah, but... Look at everything else you've taught me about since then.
Alan: I think you've just given me another very specific memory.

(Colby and David finish interviewing a suspect in his home)
Colby: So how many things about that conversation didn't you like?
David: Well, aside from cooperating before we even got in the door, confessing sideways to two felonies, and pointing us in the direction of another guy?
Colby: Yeah, aside from that.
David: A six-figure, a safe-cracker, he risks his dumb luck release...for pocket money.
Colby: I'm still kinda stuck on that comment about my shoes.

(David and Colby show up at suspect's house)
Colby: (knocks on door) Tim Pynchon?
Tim: FBI? (David and Colby look at each other)
Tim: Yeah, it's the shoes.

(Charlie is in the FBI office with an answer about how long it took the fugitives to make their escape rope out of dental floss)
Charlie: 8 to 9 months.
Liz: That's it? No bells, no whistles?
Charlie: Oh, no, I mean I tracked the rates of floss being stolen from the infirmary, allowed for a parallel escape plans, blah blah blah, but ask me what's really interesting about this rope.
David: Charlie, what's really interesting about this rope?
Charlie: Boy, I'm glad you asked.

(Charlie, Larry, and Amita describe how they can estimate how long it took prison fugitives to make a rope of dental floss)
Liz: So some... Floss math tells us when they get started so it might say something about...
(Charlie, Amita, and Larry are all looking at each other)
Liz: ...where they're going...what?
Charlie: Floss math.

David: 127 rolls of floss... Which is a restricted item in prisons for this exact reason.
Liz: Yeah, well, this and the fact that it's a great way to slice trhough someone's jugular vein.
