Once upon a time the cat bit the mouse's tail off. “Give me back my tail,” said the mouse. And the cat said, “Well, I you back your tail if you fetched me some milk. But that's impossible to do for a little mouse like you.”The mouse, however, went to the cow. “The cat me back my tail if I fetch her some milk.”And the cow said, “Well, I would give you milk if you me some hay. But that's impossible to do for a little mouse like you.”The mouse, however, went to the farmer. “The cat will only give me back my tail if the cow me some milk.And the cow me milk if I get her some hay.”And the farmer said, “Well, I would give you hay if you me some meat. But that's impossible to do for a little mouse like you.”
