Apparently there is a sociology professor who put forward the theory that we reduce our intelligence by 30% when we put a baseball cap on our heads -this becomes 60% when the cap is worn backwards

There is now a new fashion for them worn at 45% - meaning the brain is having complete out of body experience!

On the other hand I did see a morris dancer wearing one at Shrewsbury last year!

Please note - this is only a JOKE!
