Once upon a time there were three little pigs who were brothers. They lived a happy life, but they were always alert in case the big bad wolf appeared. One fine day, they decided that each would build his own house to protect himself from danger. The youngest, who was very lazy, thought it would be best to finish quickly so he could go play. 'I'll build my house of straw,' he said. 'It's very easy and I'll finish in the blink of an eye'.
