If he has to, he will not, He will if he mustn't;He does if he shouldn't And should if he doesn't.
If he can, he won't try it, If he cannot he wants to;Whatever's forbidden, That's just what he's drawn to.
You'd have him a sage, Then he'll talk like a fool;He's as cross as a saw-horse And acts like a mule.
"Who is it?" you ask, I should like to know, too,But it's your private task To take care 'tisn't you.
