The Partridge and the Fowler Lyrics

A Fowler caught a Partridge, and was about to kill him. The Partridge earnestly besought him to spare his life, saying: "Pray, master, permit me to live, and I will entice many Partridges to you in recompense for your mercy to me." 

The Fowler replied: "I shall now with the less scruple take your life, because you are willing to save it at the cost of betraying your friends and relations;" and without more ado he twisted his neck and put him in his bag with his other game. 

Moral : Those who would sacrifice their friends to save themselves from harm are not entitled to mercy.
