Probably this:

All statements are true in some sense, false in some sense, meaningless in some sense, true and false in some sense, true and meaningless in some sense, false and meaningless in some sense, and true and false and meaningless in some sense.” ―Malaclypse the Younger, Principia Discordia, Or, How I Found Goddess and What I Did to Her When I Found Her: The Magnum Opiate of Malaclypse the Younger

found here.

The Principia Discordia was a basis for a lot of the ideas in Illuminatus! by Wilson and Shea. The Illuminati card game doesn't begin to do the Illuminatus! justice.
