i'm sorry but whoever thinks that pirates would beat ninjas in a global fight to the death is clearly retarded and we can no longer be friends.
let's compare the two groups:
pirates: a bunch of middle aged drunk old men with no depth perception (eye patches) and peg-legs
ninjas: a bunch of highly trained assassins who can get in and out without ever being seen. not to mention ninja stars and that really cool outfit and smoke bombs.
sorry pirates but i am clearly on team ninja.
