In the world of mules There are no rules. - Ogden Nash

Were it not for frustration and humiliation
I suppose the human race would get ideas above its station.

Once in a night as black as pitch
Isabel met a wicked old witch.
the witch's face was cross and wrinkled,
The witch's gums with teeth were sprinkled.
Ho, ho, Isabel! the old witch crowed,
I'll turn you into an ugly toad!
Isabel, Isabel, didn't worry.
Isabel didn't scream or scurry.
She showed no rage and she showed no rancor,
But she turned the witch into milk, and drank her.

I could not eat a kangaroo. But many fine Australians do. Those with cookbooks as well as boomerangs Prefer him in tasty kangaroo-meringues.
