NCIS, Season 5

[Abby comes up to the empty squadroom late at night when no one else is there. She sits at Gibbs' desk and puts his reading glasses on.]

Abby:
[Imitating Gibbs] I heard that, DiNozzo. Another wise-ass comment like that, I'll smack you so hard, your grandchildren will feel it. [Looks at McGee's desk] Think it's funny, McGee? Wipe that smile off your face. [Looks at Ziva's desk] That goes for you, too, David. [Picks up the phone] Special Agent Gibbs! [realizes that Gibbs is behind her, slowly takes off Gibbs' glasses] You're standing behind me, aren't you?

Gibbs:
Yep. [comes over] Feeling very secure about your job, are you, Abs?

Abby:
Um, not so much anymore.
