Aight'... Listen up. It's easy, honestly.
What we have to do is make up a story with random plot.
For Example:
It was not a dark or stormy night; it was not even particularly cold. The scenery was not a hideous warped old forest but instead was the clean and pretty city of LA....
Next person adds his/her random "scene" to it:
...An old man stood up and farted loudly...
Next person follows:
...He looked at his cornfield and saw Jack Sparrow. He then scratched his butt and slowly approached Jack...
And so on..
So, Let's start the story.
It was not a dark or stormy night; it was not even particularly cold. The scenery was not a hideous warped old forest but instead was the clean and pretty city of LA..
