- Leroy Jethro Gibbs: So, how do you know Dr. Ryan?
- Leon Vance: Long story.
- Leroy Jethro Gibbs: Love to hear it.
- Leon Vance: She's an old colleague. Let's just say we spent some time together at the War College.
- Leroy Jethro Gibbs: Ah, private times?
- Leon Vance: Classified times.
- Donald Mallard: [arriving at crime scene] Interesting.
- Leroy Jethro Gibbs: Duck. Hanging or the gunshot?
- Donald Mallard: The math. For centuries hanging has used the standard dead drop, but then in 1872 an Englishman named William Marwood calculated a formula using a man's height, weight, and the distance dropped, to ensure a cleanly snapped neck.
