Brains

An Englishman, an Irishman and a Scotsman were reading a newspaper article about which nationalities' brains were for sale for transplant purposes. An Irishman's or a Scotsman's brain could be bought for £500 but an Englishman's brain cost £10,000. That proves,' said The Englishman, 'that Englishmen are much cleverer than Irishmen or Scotsmen.'
'No it doesn't,' said The Irishman, 'it just means that an Englishman's brain has never been used.'
