"Goldilocks and the Three Bears" (originally titled "The Story of the Three Bears") is a 19th-century British fairy tale of which three versions exist.The original version of the tale tells of an obscene old woman who enters the forest home of three bachelor bears while they are away. She eats some of their porridge, sits down on one of their chairs and breaks it, and sleeps in one of their beds. When the bears return and discover her, she wakes up, jumps out of the window, and is never seen again. The second version replaced the old woman with a little girl named Goldilocks, and the third and by far best-known version replaced the original bear trio with Papa Bear, Mama Bear, and Baby Bear. "Goldilocks and the Three Bears" is one of the most popular fairy tales in the English language.
