Danny: Can I help you with something?
Deeks: Just thinking about your hair. Is it bulletproof?

Callen: I'm sorry. Did I miss something? Who are these guys?
Kensi: They aren't guys. They're WODs. W-O-Ds.
Callen: Is that like a B-F-F with an S-T-D?
Kensi: W-O-D is Work Out of the Day.

Kensi: I have a boyfriend.
Deeks: So does my girlfriend.

Callen: A little piece of advice for you: Never ignore the Nellverine.

Deeks: Really? Bra holster?
Kensi: Really? Furry handcuffs?
Deeks: Little gift from our friends.

Callen: Sounds like Duncan has a girlfriend.
Kensi: Or, a cross-dressing fetish.

She wasn't born a killer. We made her one.

Callen

I like your facial hair. It makes you look like a pirate.

Eric [to Granger]

Callen: It's hard to find good friends in our line of work.
Hetty: It's hard to find them anywhere.
