The three little pigs each built a house of different materials - straw, sticks, and bricks. The big bad wolf huffed and puffed and blew down the houses of straw and sticks, but could not blow down the house of bricks. When he tried to enter the brick house through the chimney, the third little pig boiled water below and burned the wolf's bottom. The two lazy pigs then built houses of bricks and they all lived happily ever after.
