In retaliation to Underground-Rogue's Pirate Laws (which I strongly urge you to read - they're much more funny than mine).
For small-hope, who makes an awesome ninja when in need, BS who will look at this and shake her head and to Caz, because you deserve this ^^

Also to Fides, 'cause it'll piss her off.

The Code of Conduct for all Ninja:

RULE 1: No ninja will ever be seen in any colour than black

RULE 2: A ninja will be covered from head to toe in black, with the exception of a strip around the eyes for sight (though only if eyesight is truly necessary)

RULE 3: Any ninja that communicates in any other way than ambiguous hand signs will be assassinated within twenty-four hours (by the end of said assassination, only said hands that failed to communicate may remain intact, for memorial reasons).

RULE 4: A ninja's duties include sabotage, assassination, espionage and infiltration. Being hired out for children's birthday parties is not included in the above duties

RULE 5: All tactics must be underhand. To have a 'fair fight' with the enemy is shameful and degrading.

RULE 6: A ninja must float like a butterfly, sting like a bee.

RULE 7: A ninja must come and go like a shadow, leaving nothing behind but dead bodies and clothes that have bloodstain which simply won't come out.

RULE 8: While disguises are considered appropriately underhanded tactics, fairy costumes don’t count. Ever.

RULE 9: A ninja’s weapons may include katana(s), shuriken, darts, knives, yumi(s) and other assorted weapon. Any ninja carrying a ‘irate’s Sword’ needs to go walk the plank.

RULE 10: If unable to gain supernatural abilities, such as invisibility, flight, shape-shifting, inhumane speed or the ability to split into multiple bodies, pretend that you can anyway. No one fighting you is going to ask and it makes you seem cooler than you are.

RULE 11: Though recently shown in a poll that turtles are considered the ‘most ninja’ of all animals (most likely resulting from the popular children’s show: Teenage Mutant Ninja Turtles), no animal may be brought on missions – only a pirate would be stupid enough to carry one around.

RULE 12: No ninja may go into the commercial business. It takes away more than 32% of our mysteriousness.

RULE 13: When battling an enemy, never monologue. It is boring, conceited and has unfortunate results if you lose the battle.

RULE 14: A ninja must never lose a battle.

RULE 15: When fighting a pirate, be certain to pour their rum over the side of the boat. Their anger gains you an advantage in the fight and the result is quite amusing.

RULE 16: A ninja must have no emotions. If a ninja is having difficulty detaching him/herself from the situation, she/he may as well go and join the pirates.

RULE 17: Under no circumstance may a ninja have a manga produced in his/her name. EVER.

RULE 18: When using a code, do not leave the answers on the back of a page. A true ninja would use their intelligence to crack the code.

RULE 19: If you are going to die, remain as silent and mysterious as possible. If you are lucky, your opponent will be so impressed you’ll be given the opportune moment to strike in a most underhand fashion.

RULE 20: A ninja must always follow the Code of Conduct, unless said ninja has had a career change and is now a world champion chess player.
