-----------
Danny: What do you think of the name Louie?
Sheldon: I think he's gonna grow up to be a bookie.
Danny: How 'bout Clemenza?
Sheldon: Influenza. The kids on the playground will call him a virus!
Danny: Whoa, whoa! Easy! Alfonzo?
Sheldon: What'd you do, go through the cast list of God Father two?
Danny: No, these are names of people in my family.
Sheldon: You know you don't have to worry about this now. My mom and dad waited 6 weeks after I was born to name me.
Danny: Oh, they waited 6 weeks to name you Sheldon?
Sheldon: Yeah. What's wrong with that?
Danny: Now, that's cool. That's a...great name...I see you later, Sheldon. (5x19 Communication Breakdown)
----------
Mac: Don't tell me we're still playing the name game?
Danny: It's a process.
Stella: Why don't we throw Mac into the mix?
Adam: (laughs) Mac!...No. That's a great name. I like your name.
(Mac smiles. Danny's phone rings)

Flack: Two foreign pubic hair samples. Now there’s a party. (2x14 Stuck on You)
---------
Chef: They’re Peruvian centipedes (shows bowl of 5-inch centipedes). Last night was exotic seafood. Tonight, it’s creepy crawlers. Do you want to try one?
Hawkes: No! I just ate.
Chef: No, they’re not for everyone.

Stella: I do. (takes figurine) (3x07 Murder Sings the Blues)

Verna Welke: Here. (Offers Stella a colander to put on her head, Flack looks perplexed) It’s so they can’t read your mind.
Flack: We’re good, thanks. (3x08 Consequences)
---------
Flack: I don’t appreciate that, Matt. See, this here is a new pair of pants, and I don’t get uniform allowance. So I suggest you make it up to me by making the rest of this very easy (pats him for weapons). Check out what Mr. Good wrench had in his back pocket. A set of lock pick tools.
Matt: What can I say, I’m always losing my apartment keys.

Flack: You think that Houdini knew the impact he would have on Mafia Lingo?

Flack: Oh I'm sorry, can you explain the difference between RNA and DNA is that better? Because that's scintillating conversation right there.
Sheldon: It would be if you knew the-
Guy: (Walks in muttering about item being a collectors item and how they need to return it) I don't want to find out that you two pulled a Houdini on me.

Stella: Better. (1x01 Blink)

--------
Mac: (on Second Life) Hi. I like your name. (Adam turns to look at Mac disbelievingly) I love waterfalls don't you?

Stella: You have no game whatsoever.
Mac: Look, I don't need a back seat avatar.
Stella: Alright then move over. Come on, before your suspect bails. (4x05 Down The Rabbit Hole)

-------
Stella: Gotta watch yourself. All this publicity may backfire. Sinclair might just have to make you his... "deputy commissioner"
Mac: I'm very happy where I am, Stella.
Stella: That's good. It must've been satisfying seeing the look on Sinclair's face when you realized you had him.
Mac: I don't take pleasure in someone else's discomfort, Stella.
Stella: Oh.
(a slight pause, and then Mac grins sheepishly)
Mac: Yes, it was incredibly satisfying. But he'll be back, next time I'll be under an even larger microscope. Sinclair may be waiting to pounce.
Stella: Probably right, but until then, what do you say we go make a difference?
(Mac puts the newspaper in the trash can and Stella pats his back as they walk through the sidewalks) (3x23 Comes Around)

-----
(Mac does a magic trick and makes a tissue turn into a rose)
Danny: Whoa. That's impressive. It's not a butterfly but it's nice, it's good.
Stella: (as she takes the rose Mac gives her) Alright spill it. How'd you do it?
Mac: Experimentation and observation.
Stella: No, Mac, I'm talking about the mechanics of the trick.
Mac: A magician never reveals his secrets. But you're right, it's in the mechanics, the engineering. (3x18 Slight Out Of Hand)

-------
Danny: Ugh, elephant dung, are you sure?
Adam: Yeah they found it under Isabel's finger nails. It came straight from Sid
Danny: You know you've been getting some crappy case work lately
Adam: That's cute
Danny: I mean some thing like that you don't come in contact with every day. You find a connection and I'm buying you a beer
Adam: No beers on me, you have some big expenses coming up
Danny: Oh yeah? What diapers? How much can diapers cost?
Adam: Oh come on. Forget diapers I'm talking big picture here. The cost of raising a kid birth to age 18 is like 150 grand and that's not even including college
Danny: How do you know that?
Adam: Umm, my father used to remind me about it every day you know. So I would just keep all the cash if I where you. Umm, but combining your income might be less painful
Danny: Thank you Suzie Ormon
