Twenty-three. According to the Principia Discordia, the number 23 is the sacred number of the Goddess Eris and can be connected to anything in the cosmos. The first documented observer of this phenomena (dubbed "The 23 Enigma") is considered to be William S. Burroughs in Tangiers, 1960. Robert Anton Wilson and Robert Shea (whom Burroughs is reputed to have shared his observation with) included The Enigma in their Illuminatus! Trilogy.

In popular (board) culture, the number 23 most likely has something to do with either the terrible "numerology" movie The Number 23 (directed by Joel Schumacher (go figure) and starring Jim Carrey) about a set of increasingly improbable coincidences involving the titular number, OR Lost, where 23 is one of the 6 numbers that are involved in increasingly improbable coincidences within that property. It has been brought up randomly in order to connect things that have no business in being connected.
