I have chosen some of Gibbs' rules and put them into a parody of the Train song "Words." There are not enough lines to fit them all in, but rest assured, Rule 12 will make an appearance. PS, I know the second line would not really work in the song 'cause of the syllables and stuff but I couldn't think of anything else R&R! ;)

Congratulations on your employment at the Naval Criminal Investigative Service. You will be assigned to Team Gibbs working alongside Anthony DiNozzo (Senior Field Agent) and Agents David and McGee. Before you do so, a word of advice. Gibbs has a list of rules, and he expects everyone to follow them.

Follow Gibbs' rules, 'cause he hired you
First time on the job, you might forget Rule number two.
"Always wear gloves at a crime scene" and you'll be just fine.
And there's more to tell so listen well, he's really a good guy.

Rules! At first they'll shake you
Don't let them break you
Don't forget that you're still learning.
When rules make your life harder now
Use them as firewood and let them burn

And Rule number 12 is the most well-known one:
"Never date a co-worker" even if it seems like fun.
Rule 3: "Never be unreachable", 38: "Your case, your lead.
Rule 51: "Sometimes you're wrong", 15: Always work as a team!"

Rules! At first they'll shake you
Don't let them break you
Or stop your world from turning
When rules make your life harder now
Use them as firewood and let them burn

Let them burn
Let them burn
It's better to seek forgiveness than ask permission
Never bother Gibbs in interrogation

Rules! At first they'll shake you
Don't let them break you
Or stop your world from turning
When rules make your life harder now
Use them as firewood and let them burn

Rules! You'll get it right soon
Like all the others do
Even when temptation...
Makes it tricky to do what you're told
Just use them as firewood and let them burn

Let them burn
Let them burn

Thanks for reading! This song was tricky to parody...how did I do? Please be kind! PS This is a one-shot just in case it wasn't blatantly obvious.
