- Special Agent Anthony DiNozzo: Yeah. Ducky? Why would Gibbs rip his hard line out and dunk his cell phone in a jar of paint thinner?
- Dr. Donald 'Ducky' Mallard: Oh, dear.
- Special Agent Anthony DiNozzo: What?
- Dr. Donald 'Ducky' Mallard: Oh, I should have realized the time of year. It's his anniversary.
- Special Agent Anthony DiNozzo: Which marriage?
- Dr. Donald 'Ducky' Mallard: Well, the last one, of course.
- Special Agent Anthony DiNozzo: Ducky. I'm not following.
- Dr. Donald 'Ducky' Mallard: Every year, ex-wife number three gets drunk on their anniversary and calls him repeatedly.
- Special Agent Anthony DiNozzo: Why doesn't he, ah, change his number?
- Dr. Donald 'Ducky' Mallard: No idea. In case you haven't noticed, Gibbs is a man of more questions than answers.
