this a tough one. if this is sticktly a vs. battle to the death then ninjas would own.
but if this is about which would you rather be when you grow up then it would be pirates.
pirates are dope because it would be cool to pillage&plunder.
ninjas are just assassins. that can get boring after a while.
i think most of us can relate to pirtates though - they're always in search for some booty. Awhhhh yeah...feel'n on her booty. did someone say Jessicia Alba
?
