Final clubs are social clubs open to Harvard undergraduates in the senior year. Although all-female clubs have been introduced in recent times, in 1910 only male clubs existed. These were the A.D., the Owl, the Delphic, the Fly, the Fox, the Phoenix-SK, the Porcellian and the Spee, all of which still operate today. These highly exclusive organisations elect their members on the basis of their social standing, family background and savoir-faire. New members are required to go through an initiation ceremony which, despite the emphasis on social graces, often turns into a drunken brawl. Each club has its own clubhouse featuring a dining hall, library, bar and games room.
