"The argument goes something like this: `I refuse to prove that I
exist,' says God, `for proof denies faith, and without faith I am
nothing.'
"`But,' says Man, `The Babel fish is a dead giveaway, isn't it?
It could not have evolved by chance. It proves you exist, and so
therefore, by your own arguments, you don't. QED.'
"`Oh dear,' says God, `I hadn't thought of that,' and promptly
vanished in a puff of logic.
"`Oh, that was easy,' says Man, and for an encore goes on to
prove that black is white and gets himself killed on the next
zebra crossing."
