OK, here's a little something I came up on the spot with a while back and used it with unusual success.
This first happened while on IM. A HB8 one of my friends was gaming at the time happened to not get any sleep and wanted to talk. So I suggested I'd tell her a story. She couldn't help but die of laughter. She even told me the next day she dreamed the entire story.
Here's how the story went :
Once upon a time there was a handsome knight in shining armor. This knight fell in love with the king's daughter. She was of rare beauty, sophisticated and graceful.
The king, one day, organized a contest : whoever kills the dragon in the forest wins the hand of his daughter. Nobody wanted to participate, because they feared the dragon very much. Only our knight participated.
He went to the forest, in search of the dragon. He went for 3 days, until he came across a cave, rumored to be the dragon's cave. He went in. It was a dark, scary place, but nonetheless, our knight went in.
When the cave got completely dark, the dragon appeared. It was huge, intimidating, powerful beyond all imagination.
