Green Eggs and Ham by Dr. Seuss
Or here's a slight perversion of
The Clean Plater by Ogden Nash
A poet, I guess, is more or less
Preoccupied with gender.
Yet I, though custom call me crude,
Prefer to sing in praise of food.
Food,
Yes, food,
Just any old kind of food.
Pheasant is pleasant, of course,
And terrapin, too, is tasty,
Lobster I freely endorse,
In pate or patty or pasty.
But there's nothing the matter with butter,
And nothing the matter with jam,
But the warmest greetings I utter
Is for Ham
