Aesop's fables generally communicate some kind of moral message, often through the depiction of animals, who speak or otherwise take on human characteristics.

The Two Crabs

One fine day two Crabs came out from their home to take a stroll on the sand. ‘Child,’ said the mother, ‘you are walking very ungracefully. You should accustom yourself, to walking straight forward without twisting from side to side.’

‘Pray, mother,’ said the young one, ‘do but set the example yourself, and I will follow you.’

Example is the best precept.
