I found the Mp3 of this story for free here, and it's well worth a listen.
Skeleton tells a story of a man whose bones ache and bother him terribly, as a hypercondriac nobody really listens to his complaints.
He goes to a bone specialist, who tells him he is not ready yet for the treatment. The aching in his bones becomes an internal struggle between the skeleton and the man, the more the man worries the more weight he loses so the more the skeleton wins. He believes the skeleton is trying to escape, to control him. As the pain gets more and more the struggle continues, until in a moment of desperation he calls in the bone specialist to fix up the problem.
