Book excerpt: The laws of rugby are as extensive as they are confusing, their nuances and interpretations argued over relentlessly by rugby fans around the world and virtually impenetrable to those who are new to the game. In an effort to provide some much-needed clarity, Paul Williams takes an irreverent, hilarious, p*ss-taking tour through the labyrinth that is rugby's rule book – or, for the pedantic, rugby's law book. Hilarious, off-beat and (surprisingly) insightful, this is the perfect gift for rugby fans all around the world.
