Facts:

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

Testimonial:

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.)

n. A warrior originating from feudal Japan who specializes in the art of stealth, assassination, sabotage, and molesting people without them even noticing. Ninjas are around anymore, but the term can still be used to describe one who is very sneaky, clever, sly or just a bad ass in general.

Here are a few requirements a Ninja would have had to live up to when they were active:

1. Ninjas must be able to make themselves unnoticeable in a empty room painted top to bottom in white.

2. Ninjas must be able to remain submerged in water for up to 7 hours minimum.

3. Ninjas must be able to survive a one-on-one fight against Chuck Norris for 6 WHOLE seconds.

4. Ninjas must be able to hold in a fart for 3 months

5. Ninjas must have an 11 inch penis MINIMUM. THIS WAS MANDATORY

6. Ninjas must be able to stop their own pulse for up to a week.

7. Ninjas can read a person's mind and memories just by staring at them

8. If a Ninja is captured, they must find a way to kill themselves.

9. Ninjas are expected to be able to get a 100% on every song on Expert mode in Guitar Hero 3. Failure will result in immediate execution.

10. A Ninja must have watched and memorized Nigahiga's "How to be Ninja" video
