NCIS, Season 1

[Gibbs and Tony, with Kate behind, are making their way to the plane]

Tony:
Just accept the fact that you're gonna get lost.

Kate:
Why do you assume I'm going to?

Tony:
Because everyone does. [Gibbs looks back at Kate] A carrier's a big and confusing place first time on board.

Kate:
Duly noted.

Gibbs:
Numbers are stenciled on the bulkhead. First one tells you the deck level, they're called bullseyes.

Kate:
Deck level.

Gibbs:
Second one, the frame number. Third tells the compartment's position in relation to the ship's center line. Last letter tells you what the space is used for.

Tony:
Crossing from port to starboard to starboard to port isn't as simple as going straight across.

Gibbs:
Sometimes you gotta go up one deck and down another.

Tony:
Or down one deck and up another.

Gibbs:
Sometimes two.

'Tony:
Frustrating.

Gibbs:
Not to mention confusing. [smiles at Kate] But you'll get the hang of it.

[Kate is looking confused and overwhelmed]

Tony:
After you get lost a few times.

[Kate nervously looks on]
