Question about a NCIS episode?

I remember an episode of NCIS where McGee and somebody (It was either Abby or Kate, not sure which) were calculating a woman's measurements and DiNozzo walks in and he's like "She was like what, 5'11", which would make her about 135 pounds." (That's a guess, it may be different. xD) and they tell him to shut up 'cause they're working. They finish their calculations and he turns about to be right. They turn to him and he's already doing something else. The more I think about it, the more I think it's Kate and McGee, but I'm not sure. Does anybody know what episode this is from? I'd really appreciate it.
