You always hear about "Gibb's Rules" on the show. Anyone out there know what all of them are and how many?

link

This website has all the rules that have been mentioned so far, including when they were stated and the quote/conversation that goes with it. It also has some of the rules that other people have made, such as Tony and Abby, when they talk about making their own rules.

Here is what I got. Some are doubled. Maybe a mistake por the writers but here are the ones I've heard. The episode where they were mentioned is seguinte to the rule.
1. Never let suspects stay together. (Yankee White)
2. Always wear gloves at a crime scene. (Yankee White)
3. Don't believe what you're told, always double check. (Yankee White)
3. Never be unreachable. (Deception)
4. Never say you're sorry.
5. If you have a secret, the best thing is to keep it to yourself. Second-best is to tell one other person if you must. There is no third-best. (Blowback)
7. Always be specific when you lie. (Reveille)
8. Never take anything for granted. (Probie)
9. Always carry a knife. (Missing)
10. Never screw over your partner. (Blowback)

13. Never ever involve lawyers. (Collateral Damage)

22. Never interrupt Gibbs during an interrogation. (Smoked)
23. Never mess with a Marine's coffee if you want to live. (Forced Entry)
26. Never apologize - it's a sign of weakness.
27. Never eat in autopsy. (Switch)

Ok i have this app on my ipod that is called "Gibb's Rules" and it names all the rules for you and even more. Oh and the app is also free!

There is no actual website of any sort but there is this great list made por fãs that is updated quite well. It can be found link. Hope this helps :)

ill do my best.

Rule 1. Never let suspects stay together, it'll give them a chance to make up a believable story (Yankee White)

Rule 2. Always wear gloves at a crime scene. (Yankee White)

Rule 3. Never believe anything you're told, double check. (Yankee White)
...
Rule 7. Have a faca at all times (One Shot, One Kill)

Thats all i can think of off the topo, início of my head

You have to watch the show because they name some of them in certain episodes.And i guess they make up make them up as they go along because they never reveal them all at onces. They also does reveal them in chronological order, they just say them when something that lates to them come up. Last but not least they have not said how many rules there are in any episode.

Not long after Ziva joined NCIS, she broke a rule (unknowingly). They went to the "conference room" and she asked how many Gibbs rules there were. Gibbs responded that there were approximately 50. Ziva then asked if they were written down somewhere and Gibbs said "no". The rules have been written down por various fãs over the seasons, but it would appear that even the writers don't have a solid list of what rules are what number. Often two (or 3) rules are listed por the same number. And there are some "rules" that aren't actual rules (ie "never say you're sorry").

There are # 51 mais or less. I named them somewhere else on this site.
