Could it be in two stages :
1. ask people to create a cartoon drawing of what happens next and share /upload to shared online space
2. Each person or group is then allocated 6 of these images at random, not sure how this would work online but f2f you would shuffle and distribute (ideally having photocopied so same images can turn up in different sets) then ask people to organise their set into a sequence ie storyboard and tell this version of the story. Then share and discuss!
Lots of scope for multiple meanings and re-interpretations?
