Jack and the Beanstalk
Once upon a time, on a little farm, there lived a boy named Jack. He lived on farm with his mother, and they were very excluded from the normal circles of economic activity. This cruel reality kept them in straits of direness, until one day Jack's mother told him to take the family cow into town and sell it for as much as he could.
Never mind the thousands of gallons of milk they had stolen from her! Never mind the hours of pleasure their animal companion had provided! And forget about the manure they had appropriated for their garden! She was now just another piece of property to them. Jack, who didn't realize that nonhuman animal have as many rights as human animals - perhaps even more - did as his mother asked.
On his way to town, Jack met an old magic vegetarian, who warned Jack of the dangers of eating beef and dairy products.
