Classic Poem

True Cherubs never run in Debt
Because of Clothes and Things,
For, like some Chickens I have met,
They're built of Heads and Wings.

And Scientific Pens and Tongues
Have made it very clear
That Cherubs, since they can't have Lungs
Must always Sing by Ear.

But none of them, 'tis understood,
Will play a Naughty Prank;
And this is good, because they would
Be Difficult to Spank.
