The dog and the bone

A naugty dog stole a bone from the butcher.
He scampered away and onto a bridge that crosssed a stream.
And he saw another dog ih the water which has a bone in his mouth.
As it looked bigger than his ,he wanted it.
When he barked the dog, his bone slipped out and fell into the water.
All he could see was himself andno bone ,either.
And the moral is...
Be happy with what you have.
