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.
