A small sparrow shivered while snow fell all around him. The sparrow would surely die in the cold. Then a cow wandered along and defecated on the sparrow. Warmed by the cow pie, the sparrow stopped shivering and began to sing. A passing cat heard the sparrow's joyful song and ate him.
Moral: Not everyone who shits on you is your enemy. Not everyone who gets you out of shit is your friend. And, if you are up to your neck in shit and can still manage to be happy, for Heaven's sake keep your mouth shut.
