You may have heard about the age old dispute that the ninja have against their natural enemy, the pirates. If not, it's an internet thing.
Here I have laid out a few of the basic facts about them.
Pirates: Are pluralized with an S, just like most nouns.
Ninja: Can be pluralized with either an S or be simply staying the same.
Edge: Ninja. And they get +5 awesome points as well.
Pirates: Have their own holiday, National Talk Like a Pirate Day.
Ninja: Keep their holiday private, yet invisibly written on everyone's calendar. No one knows when it is.
Edge: Tough to say. Holidays are better if you know about them, and funny accents are cool, so I say pirates win this one.
Pirates: Have their own language on Facebook. It's called "English (Pirate)" on the drop down menu.
Ninja: Have no Facebook recognition.
Edge: Pirates. Duh.
Pirates: Have Jack Sparrow.
Ninja: Have Naruto.
Edge: Pirates. And it's 'Captain' Jack Sparrow.
Pirates: Fight using a combination of skill, luck, and dirty tricks.
Ninja: Fight using highly honed reflexes, with skill bordering on magical.
Edge: Ninja. Both styles are very cool, though.
Pirates: Drink too much.
Ninja: Train too much.
Edge: Ninja. Drinking too much is kinda lame. Training too much is often lame, but can be cool.
As you can see from this, it's a bit of a tie. Ninja are virtually unstoppable, though, so in a direct fight I would say that the ninja would win. Unless it was a fight with Captain Jack.
