I see the scene but can't remember episode's name. I'm reptty sure it's season 3, but maybe I heard it wrong. Or misunderstood the number. I was pretty damn sure I heard "14", though.

Looked it up on the Gibbs rules side and, seems the one I had in mind is another #1 (http://cbsncis.wetpaint.com/page/The+Rules) so... Now I'm confused.
