Possesed by ALL true ninjas, real ultimate power is the ability to flip out all the time and kill people for practically no reason at all.
If you don't believe that ninjas have REAL Ultimate Power you better get a life right now or they will chop your head off!!!

See ninja.
My friend Mark said that he saw a ninja totally uppercut some kid just because the kid opened a window.
And that's what I call REAL Ultimate Power!!!!!!!!!!!!!!!!!!

What all ninjas have and they show it when they're choping off dudes heads, throwing ninja stars at peoples faces, fliping out hard, poping boners, making out with hot ninja babes, and wailing on their guitar.
Ninjas are so awesome, their strongest weapon is their boners!!!!

I wanna be a ninja when I grow up!
