A man went in for a Brain transplant operation and was offered a choice of two brains by the surgeon. He could choose either the Architect's brain which would cost him £10,000 or the Politician's which was £100,000.
'Does that mean that the politician's brain is much better than the Architect's?' exclaimed the clearly puzzled man.
'not exactly' replied the surgeon, 'the politician's has never been used.'
