TV Show:










Below are the rules that NCIS has provided over its many years on the air.  I will add more to the list as they come available.






The following are the rules that Gibbs lives by - the Boss. These rules are the ones that need to be obeyed at all times.

If these rules are not followed then the consequence is a slap to the back of the head.  (Yes, that means you DiNozzo)!

(Please don't change the rules to what you think they SHOULD be! This is a list of what the rules ARE! (As told on the show)
