In the episode A Weak Link, why does Gibbs get out of the car with his pants undone?

Haha, it might have just been a mistake! He probably forgot to zip it up!

I just wre watched this episode. It looks like he unzipped them to tuck in his shirt...I guess with a 带, 皮带 and everything it is difficult to tuck in your 衬衫 without unfastening. Don't ask me why it was in the scene that way though :)

He was just re-tucking in his shirt.

gibbs was with his lady friend, the undone pants was meant to suggest he was being serviced on the ride over. #beej
