The Inaugural Body in Mind Riddle Competition

See if you can solve this riddle.  A picture, they say, tells a thousand words. This one doesn’t tell that many but if you can work out what it is saying, we will give you are prize….

The hint: We are starting a series of new experiments, each item in this picture contributes to a description of what the experiment is about.  There are actually two copies of Painful Yarns. Metaphors and stories to help understand the biology of pain: one for the correct answer and one for the answer that we like the best. We like things that are clever and funny.  Good luck.

Update

Great suggestions. Great ideas. Not on the money – although Ian’s at least in the same book if not the same page….. Keep guessing folks – there is are no easy rides!
