I am ashamed to say I have only recently discovered the invisible pink unicorn - rival to the flying spaghetti monster. And possibly a more sophisticated deity, as, like the Judeo-Christian God, it involves profound mysteries - such as the mystery of how it can be both pink and invisible. In the words of an early follower:
"Invisible Pink Unicorns are beings of great spiritual power. We know this because they are capable of being invisible and pink at the same time. Like all religions, the Faith of the Invisible Pink Unicorns is based upon both logic and faith. We have faith that they are pink; we logically know that they are invisible because we can't see them."
The invisible pink unicorn "raptures" socks - which explains why they go missing.
