I just came up with this just a minute ago. I think you know what to do. Just put some rules that you think all shippers should follow when it comes to Tony/Ziva.

Rules

1. Always find the best in every situation.
2. Prepare for the worst, but never expect it.
3. Have faith, it can move mountains.
4. Know that no matter what they have always had and will always have each other's backs.
5. A look can say it all.
6. Remember that in our world Rule #12 doesn't exist!
