The football match in Tom Brown’s Schooldays, slightly annoted by Wes Clark, but not in a useful way. Unfortuantely I cannot really pick out much in the way of fair play, or indeed rules in this game.
What is potentailly more important is the afternath of said game where the kids all went off for a slap up meal, sang heartily and did a serious amount of underage drinking. Something which JK Rowling is well aware is a key point of all public school sagas.
