Right, I saw this on the Critical Anaylsis of Twilight spot and I'd thought it would be good fun here.

What you have to is BASICALLY write three words at a time to make the story.
Example:

1st person: One day, Bella..
2nd person: ..was kissing Edward..
3rd person: ...while Jacob was..
1st person: ...eating smelly cabbage..

You get the idea... With Harry Potter and Twilight characters in it so they can do all the CRAZY stuff they normally do..

I'll start:

One day, Harry..
