Fred: I have a problem. Uh, Anthony DiNozzo, Sr. is not only staying in a $1,500-a-night suite, he's also running up a huge tab. Spa treatment, manicure, room service, French champagne, and I just got a call, he's ordered a limousine for tonight.
Gibbs: Guess you haven't got the bill for the flowers yet?

Torres: Oh, we’re federal agents!
