"The Invisible Pink Unicorn (IPU) is a being of great spiritual power. We know this because she is capable of being invisible and pink at the same time. Like all religions, the Faith of the IPU is based upon both logic and faith. We have faith that she is pink; we logically know that she is invisible because we can't see her." (from wikipedia and other sources)
This is a community meant for those who believe the existence of the IPU as likely as any other theology.
