Once upon a time there was a person who thought up a story. The story was filled with knights and dragons and damsels in distress. Then the person thought to tell others his story. Someone heard the tale and thought of a new adventure the knight could go on. Now the new person went and told his story of the knight slaying beasts. Hearing the story another person thought "How would the dragon feel?" and created a brand new story about the dragon's travels. And the chain goes on and on and on.
