In one of Aesop’s Fables, a donkey walking through the woods finds the skin of a lion. Hunters had killed the lion and left the skin to dry in the sun. The donkey put on the lion’s skin and was delighted to discover that all the other animals were terrified of him and ran away when he appeared. Rejoicing in his newfound respect, the donkey brayed his happiness—only to give himself away by his voice. The moral of the fable was clear: fine clothes may disguise, but silly words will disclose a fool.
