OLIVER INSIST

Oliver was always trying to insist,
To eat the things not on his diets list,
His body was so round,
His health was unsound,
He didn't listen to his nutritionist.

Oliver thought his gorging was nifty,
But he never saw his birthday at fifty,
Still, under the ground,
His appetite's sound,
He smells fast food when the wind's a bit shifty.
