[McGee is innocently drinking coffee that Tony gave him without mentioning that it belongs to Gibbs]

Leroy Jethro Gibbs:
Enjoying that coffee, McGee?

Timothy McGee:
Uh, yeah!

Leroy Jethro Gibbs:
It's not too hot?

Timothy McGee:
[pause] It's your coffee. I'm, uh... Sorry, Boss. I'll get you another one. [to Tony and Kate] Thanks.

Caitlin "Kate" Todd:
Yeah, maybe next time you should remember Rule Twenty-Three.

Tony DiNozzo:
Is that the one about not marrying a woman who eats more than you do?

Marine Sgt. Chris Hegarty:
You never mess with a Marine's coffee, if you want to live, Agent DiNozzo.

Tony DiNozzo:
[laughs] That's right. [as McGee leaves] Dead man walking!
