Here's the story Erik told me at bedtime tonight:
Once upon a time there were four little pigs and four big bad wolves. All the pigs had houses. The wolves blew them all down. They went in the houses and tried to eat the pigs. The pigs ran away. The wolves ran after them and tried to eat them again. One pig built his house of bricks. The other pigs built their houses of straw. The pig went to bed and dreamed the big bad wolf turned into a big nice wolf. And it came true! Then there were four big nice wolves. They didn't blow the houses down. The end.
