One of the reasons why I love ultimate frisbee as a sport is its inherent honour system. Here's the quote from the Ultimate Handbook: "In Ultimate, every player is responsible for their own conduct on the field. There's no refs to make sure that everyone acts like grown-ups, so it's the responsibility of players to call fouls on themselves if the person they have fouled does not call the infraction. That's right. You can call a foul on yourself. Ultimate relies on the honour system and the belief that no one will intentionally cheat, much like marriages, the income tax system, and all-you-can-eat sushi bars." I'm thinking of organizing an ultimate frisbee day this Independence Day...
