1. Ninjas are mammals.
2. Ninjas fight ALL the time.
3. The purpose of the ninja is to flip out and kill people.

Weapons and Gear:

Ninja sword
Throwing stars
Ninja outfit


Ninjas can kill anyone they want! Ninjas cut off heads ALL the time and don't even think twice about it. These guys are so crazy and awesome that they flip out ALL the time. I heard that there was this ninja who was eating at a diner. And when some dude dropped a spoon the ninja killed the whole town. 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!!!!!!!!!!!!!!!!!!

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!!! It's an easy choice, if you ask me.

Ninjas are sooooooooooo sweet that I want to crap my pants. I can't believe it sometimes, but I feel it inside my heart. These guys are totally awesome and that's a fact. Ninjas are fast, smooth, cool, strong, powerful, and sweet. I can't wait to start yoga next year. I love ninjas with all of my body (including my pee pee).

Q and A:

Q: Why is everyone so obsessed about ninjas?

A: Ninjas are the ultimate paradox. On the one hand they don't give a crap, but on the other hand, ninjas are very careful and precise.

Q: I heard that ninjas are always cruel or mean. What's their problem?

A: Whoever told you that is a total liar. Just like other mammals, ninjas can be mean OR totally awesome.

Q: What do ninjas do when they're not cutting off heads or flipping out?

A: Most of their free time is spent flying, but sometime they stab. (Ask Mark if you don't believe me.)

Ninja is a game in which two or more people must play. The game is played by slapping each other on the hand. You can only make one move per turn. Once an attempt at slapping the other person's hand is made, you must keep your body in that position until your next turn.
Person 1: Dude, my hand hurts from that Legit game of Ninja!

Person 2: Hella yeah it does, I pwned you in Ninja!

Due to the fact we could not find any ninjas, we can not define them. We hope our apology is accepted. (But not by ninjas, for they never forgive, and they NEVER forget.)
That ninja is a great ninja, for we do not know what, who, or where it is.
