A lion met a tiger
As they drank beside a pool
Said the tiger, “tell me why…
You’re roaring like a fool.”
“That’s not foolish;” said the lion,
With a twinkle in his eyes,
“They call me king of all the beasts
Because I advertise!”
A rabbit heard them talking,
And ran home like a streak.
He thought he’d try the lion’s plan,
But his roar was just a squeak.
A fox, who happened on the scene,
Had a fine lunch in the woods.
The Moral? When you advertise,
Just be sure you’ve got the goods.
