Ziva, McGee and others in “Double Identity”

Ziva

Hey, any of you notice something different about Ducky?

McGee

Yeah, he has seemed awfully chipper as of late.

Tony

Ducky does seem plucky. No one loves rain in D.C.

Ziva

No, his ties! He's been wearing tie ties, not his bow ties.

Tony

Wow. That's very observant.
