Kate Moss is at the top of mountain, looking down, when suddenly she slips, and starts falling down, down, down....

But as she falls, she realises that amazingly, she's missing all the boulders and rocks that litter the sides of the mountain. When she finally stops falling, she gets up, and finds that she's totally uninjured.

And the moral of this story is...?

A rolling Moss gathers no stones.
