The Weasel And The Man
Man once caught a Weasel, which was always sneaking about the house, and was just going to drown it in a tub of water, when it begged hard for its life.
It said to him, "Surely you haven't the heart to put me to death? Think how useful I have been in clearing your house of the mice and lizards which used to infest it, and show your gratitude by sparing my life."
"You have not been altogether useless, I grant you," said the Man: "but who killed the fowls? Who stole the meat? No, no! You do much more harm than good, and die you shall."
