从前，有个主人养了一只山羊和一头驴子。
主人总是给驴子很多食物，这让嫉妒心重的山羊很不高兴。
有一天，山羊对驴子说：“你整天都在推磨、背东西，太辛苦了！不如假装生病，摔倒在地上，这样就可以休息了。”
驴子听从了山羊的建议，结果摔得遍体鳞伤。
主人看到驴子受伤，就请来医生治疗。
医生说要将山羊的心肺熬汤作为药给驴子喝才能治好。
于是，主人杀掉了山羊，用它的内脏去治好了驴子。
这个故事告诉我们，那些想做坏事的人，最终只会自食其果。
Once upon a time, there was a master who had a goat and a donkey.
The master always gave the donkey a lot of food, which made the jealous goat very unhappy.
One day, the goat said to the donkey, "You work so hard all day pushing the mill and carrying things. Why don't you pretend to be sick and fall down on the ground? Then you can rest."
The donkey followed the goat's advice and fell down, getting hurt all over.
When the master saw the injured donkey, he called in a doctor for treatment.
The doctor said that the goat's heart and lungs had to be cooked into soup as medicine for the donkey to get better.
So the master killed the goat and used its organs to heal the donkey.
This story teaches us that those who try to do bad things will only end up harming themselves.
