The Three Little Pigs is a fable/fairy tale featuring anthropomorphic pigs who build three houses of different materials. A big bad wolf blows down the first two pigs' houses, made of straw and sticks respectively, but is unable to destroy the third pig's house, made of bricks. Printed versions date back to the 1840s, but the story itself is thought to be much older. The phrases used in the story, and the various morals drawn from it, have become embedded in Western culture.
