We did this in my creative writing class. We had to write a few sentences and then pass our story to another person until everyone had written a part of it. The last person to have it had to end it. Each change in font represents a different person's part of the story. Laura is some girl in the class. She babysits a little boy that gets a cookie every time he goes potty. And yes, that is somewhat important to know.
We also did some Accordion Poetry (we could only see the line before us, not the rest of the poem, so it turned out... interesting... Each line is by a different person).
