Other Cricket Unwritten Rules
Many of the game's unwritten rules - don't bowl bouncers to tailenders, don't run two on a lame fielder's arm and don't Mankad - were expunged from the un-book during the reigns of the ruthless West Indies and Australian teams. Leaving? Don't run out an injured batsman who is out of his crease, don't take an over-throw if the ball hits a batsman and don't take your mum's weight-loss pills. -- Richard Hinds
