Ian..if you are familiar with 'pataphysics, demonstrating that "a metaphorical one could equal a metaphorical two." might be an easy exercise.

(I found that page by searching for the famous quote "God is the tangential point between zero and infinity.")

I also loved the hypothetical question I found on a toilet wall at the Univ. of Kansas years ago... "Can a metaphysican be sued for malpractice?"
