NCIS, Season 2

[The team arrive at the crime scene.

Gibbs:
Break out the gear. I'll coordinate with the MPs. [hands coffee to Tony] You drink that, DiNozzo, you're dead.

[...]

Tony:
[hands Gibbs' coffee to an oblivious McGee] Coffee, Probie. Looks like you could use it.

McGee:
Oh. Thanks, Tony.

Tony:
Don't mention it. [smiles as he walks away]

McGee:
[to Kate] I think he's finally starting to warm up to me.

[Kate looks away and smiles]

[...]

[McGee enters crime scene sipping the coffee just as Gibbs is walking out]

Gibbs:
Enjoying that coffee, McGee?

McGee:
Uh, yeah.

Gibbs:
It's not too hot?

[Kate and Tony smile at each other. Gibbs glares at McGee and walks away. McGee spots Kate and Tony laughing quietly to each other and realizes he has been pranked.]

McGee:
[embarrassed] It's your coffee. I'm sorry Boss. I'll get you another one. [turns to Kate and Tony] Thanks.

Kate:
Yeah, maybe next time you should remember Rule 23.

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

MP Sgt. Hegarty:
Never mess with a Marine's coffee, if you want to live, Agent DiNozzo.

Tony:
[laughs at McGee] Yeah.

[Kate pats McGee's back as he walks out the door]

Tony:
Dead man walking!
