Herschelle Gibbs became the first man to hit six sixes in an over in international cricket when he took the Holland bowler Daan van Buge apart at St Kitts in the 2007 World Cup. And the South African's achievement cost Johnnie Walker -- or rather their insurerers -- about £515,000. The whisky firm had pledged this amount to charity for anyone making six sixes. The lucky recipient was Habitat for Humanity, the British organisation set up in 1976 to help tackle poverty housing on a global scale.
