Read Along or Enhanced eBook: This story opens with "There once was a man whose house was very small," and it continues, "It was cluttered with things from wall to wall." With a tiny, cluttered house, giggling children, and a snoring wife, the poor man can't get a good night's sleep. If only, he thinks, I had a big quiet house! He throws off his covers and goes to visit the wise old woman at the edge of the village. Surely she can help him solve his problem. And she does, but not without giving him some very unusual advice. “Bring a chicken into your house,” she suggests.

The ending of the story proves, as so many ancient folktales do, that quite often, nonsense makes the best sense of all.
