Ogden Nash (August 19, 1902 – May 19, 1971 / New York / United States)

OR
The Child Is Father Of The Man, But Not For Quite A While

So Thomas Edison
Never drank his medicine;
So Blackstone and Hoyle
Refused cod-liver oil;
So Sir Thomas Malory
Never heard of a calory;
So the Earl of Lennox
Murdered Rizzio without the aid of vitamins or calisthenox;
So Socrates and Plato
Ate dessert without finishing their potato;
So spinach was too spinachy
For Leonardo da Vinaci;
Well, it's all immaterial,
So eat your nice cereal,
And if you want to name your ration,
First go get a reputation.
