The ass's brains

The lion and the fox went hunting together. The lion, on the advice of fox, sent a message to the ass, proposing to make an alliance between their two families. The ass came to the place of meeting, overjoyed at the prospect of a royal alliance. But when he came there the lion simply pounced on ass, and said to the fox: "Here is our dinner for today. Watch you here while I go and have a nap. Woe betides you if you touch my prey." The lion went away and the fox waited; but finding that his master did not return, ventured to take out the brains, and asked the fox in a terrible voice: "What have you done with the brains?" "Brains, your Majesty! It had none, or it would never have fallen into your trap."

Moral lesson: Wit has always an answer ready.
