In the Pilot episode, Auggie's excuse when Joan calls him out for being so quick to defend Annie? "She likes Mingus."
Even funnier given that "Mingus" is one of Auggie's known aliases.
Annie's sister walks in on her holding a can of ice cream to her sore head after a fight. Annie blows off her concern and lightly calls it a "stapler accident." Yeah. Annie just claimed to have accidentally stapled herself in the back of the head. Try to picture that one!
Joan doing jury duty, and Auggie getting her out of it in less than 10 seconds when she finally admits she needs to.
To be precise; Joan, the DPD's queen of poise, being hilariously awkward and ineffectually trying to hide her phone conversation, only to be called out—several times—by an extremely acerbic female judge. She just comes across as a complete ditz!
Arthur, head of the CIA's Clandestine Operations Division, is very confused as to whether the meeting has been rescheduled or if that was the meeting. His facial expression really helps sell it.
Jai and Joan's conversations during "The Outsiders." He really didn't want her to know that they couldn't get the helicopter working.
Jai: Our situation on the ground requires us to be very creative.
After losing a lot of money at craps, intentionally (and, ironically enough, almost failing to do so as she suddenly won 30.000 dollars betting on snake eyes; Auggie's astonished expression is gold), Annie is talking to the woman they're hoping will try to turn her:
Annie: My sister's husband lost his job a couple of months ago, so they... they burnt through all their savings, I don't have anything, I don't have anyone to go to... *increasingly emotionally* I'm totally screwed, God! And if I can't leave the country, I'll probably lose my job, — I mean I have to tell them why I can't come back, and my TOOTH hurts!
Auggie brings little American flags to work on Independence Day. Annie tries to freak him out.
Annie: These are cool, where'd you get North Korean flags?
When Auggie and Eyal finally meet face-to-face. Doubles as heartwarming.
Eyal: I wasn't expecting you to be—
Eyal: —so short.
Auggie: Oh, well I wasn't expecting you to be so handsome.
Eyal:(to Annie) I like him.
From "Glass Spider"; Joan and Arthur, plus Auggie and Barber in the surveillance van, all tensely listening to insanely cheery carousel music through Annie's wire.
Joan: Do you remember that first weekend we went away together? (beat) Secretly.
Arthur: Chesapeake. How could I forget? I claimed to be going to a conference, and you asked for vacation time.
Arthur: Why do you ask?
Joan:(grins) Annie and Auggie just pulled the same move. I think they're dating.
Arthur:(also grins) Well, we thought it might happen.
Think about that for a minute. Joan and Arthur have been shipping Annie and Auggie all along!
Also from "Vamos":
Auggie: Morning, Walker. How was your evening?
Annie: I didn't get much sleep. I just... tossed and... turned...
Auggie: Interesting. Me, too.
Calder: What happened to your shoulder?
Auggie: What, this? Shaving accident. (smirks) -You should see the other guy.
Calder: There was another guy?
"Dig for Fire": Annie needs a bandage after her fight with Seth Newman.
Auggie: (picks up a piece of tape) -Now, where does this go?
