I don't even...

why not both?

YAAAAAAAARRRRR only pirates get wenches

Obviously ninja, pirates suck

NINJAS DON'T GET STUFF FOR FREE FROM THE INTERNET

I am the alpha and the omega.

If I were a pirate I'd probably be British.
If I were a ninja, I'd prbably be Japanese.

Therefore, as a pirate I'd get tea, I'd get all the ladies with my sexy accent (assuming we go by pirates at the time of the Spanish armada, Scotland and Wales aren't sailing around yet, so by "British", I mean "English" and of the British Empire), I get to rape and pilliage and sail the seas as a free man with nothing to worry abotu but the loyalty of my crew.

As a ninja (let's be fair and say at aroudn the same time period as the pirate), I would have to follow the orders of my superior, and train relentlessly to hone my skills. I'd get paid for my work, I'd have to have self disipline and never be caught off guard. If I ever had my loyalty questioned, I'd have to end myself.

Er, Pirate please.

Would you rather:

Be able to fly for intervals of one hour on Saturdays and Sundays. Top speed 40mph and if you don't land before time is up you just drop out of the sky at the same momentum.

or

Be able to morph into anyone/thing for intervals of 10 minutes on any day. When the time is up you turn back into yourself on the second, but you are ass naked.

be a cowboy!

well, a pirate life would be fucking boring, cause you don't raid ships and forts everyday so you'll have months sailing around eating crackers. but being a ninja means i'll have to be a small Japanese peasant

Might as well have just asked would you rather be Somalian or Japanese

The only thing that would suit me for being a ninja is the fact that I do parkour. The problem is that I am Irish, not Asian and I'd feel out of place.

Well a Pirate that knows Ninjitsu would be pretty cool, so would a Ninja with a Parrot and a peg leg.

Pirate.
