You need to watch Unlimited Blade Works to understand it.
A character called Archer chants this to produce what is known as one of the most epic fight scenes in anime history:
I am the bone of my sword
Steel is my body and fire is my blood
I have created over a thousand blades
Unknown to Death, Nor known to Life
Have withstood pain to create many weapons
Yet, those hands will never hold anything
So as I pray, unlimited blade works.
Now, make a parody!
I'll start with one that was handed into an English poetry exam. (Not by me, I swear it.)
I am the bone of my essay,
Procrastination is my body, and caffeine is my blood.
I have ignored over a thousand deadlines.
Unknown to spellcheck, nor known to passing grades.
Have withstood responsibility to fail many classes,
Yet those classes with never teach anything.
So as I hand in...UNLIMITED ESSAY WORKS!
