Apple Poem by Tin Can

The humble apple is a thing of beauty.
It even has a sense of duty.
For eating one a day, they say,
Quite possibly, keeps the doctor away.

So..., here we have a medical plight.
Implying, the humble apple simply just might,
Have hidden properties within its core,
That could well produce a definitive cure.

In the, 'Garden of Eden, ' the apple became,
The unlikely pawn in a religious game.
Opening the cloudy eyes of man,
A devilish dish served as Satan's plan.

Again we encounter the medical plight,
Linking the apple with the gift of sight.
But proven not, so thus cannot be said,
Apples can heal, be they green, gold, or red.

What we do know, and know quite well,
Is the historical story of one, William Tell.
Who shot an apple from the head of his son,
In fear of execution for what he had done.

And as an apple fell from a tree,
It gave Sir Isaacs Newton his theory.
The theory of universal gravitation,
As well as that of the earth's rotation.

And names adopted such as the city, New York.
Known as the, 'Big Apple, ' in conversational talk.
A name taken merely by chance.
Popularised by a whimsical dance.

'Apple of my eye, ' is an age old saying.
A term of endearment, when relaying.
But again with reference to the organ of sight,
I wonder. Could my apple theory, be right...?
