NCIS, Season 8

McGee:
[exiting the elevator] Ah, I missed these stained orange walls. God bless tacky American bureaucracy.

Tony:
The prodigal probie returns.

McGee:
You know, I realized something, Tony. You don't appreciate something until it's gone.

Tony:
So you missed me, ay?

McGee:
No, other things, like breakfast without beer.

Ziva:
I thought that was the Irish.

Tony:
Canadians, too.

McGee:
You know, beer doesn't go well with either eggs or oatmeal. [looks at Ziva] Why are you so tan?

Ziva:
Why are you so white?

McGee:
I've always been like this.

Ziva:
It becomes you.

McGee:
You're lying.

Ziva:
Through my teeth.
