By forming the Princeton Dueling Society, of course:
The mission of the Princeton Dueling Society is to preserve the thin fabric of civility that unites and defines the well-bred young men and women of Princeton. Too often, conflicts are settled in the most uncouth manner: fisticuffs, poison, and other dastardly methods are not uncommon. The Princeton Dueling Society offers a forum for settling disputes in a civilized manner, with terms agreed upon by both parties. Participants are expected to conduct themselves in an honourable manner and to accept the outcome of the duel as conclusive. Once a person has demanded satisfaction and been met on the field of honour, his honour and the honour of his opponent is beyond contestation.
