The Babel Fish is small, yellow, leech-like, and probably the oddest thing in the Universe. It feeds off of brainwave energy, and as a by-product, excretes telepathically, the intended meanings. The outcome of which is that if you stick a Babel Fish in your ear, you can instantly understand anything said to you, in any language. The Babel Fish is, or rather was, the centre of a major controversy. The chances of anything so mind-bogglingly useful evolving by chance can be considered a positive proof of the existence of God. This causes other, greater problems. As God will refuse to prove that he exists, as proof denies faith, and without faith He is nothing, He is confronted with a problem. The Babel Fish is a dead giveaway - it proves that He exists, and therefore He doesn't! God was reported to have vanished in a puff of logic at that point. As the Babel Fish is now widely available from any convenient Sirius Cybernetics Corporation 'Babel Fish Dispenser Aquarium', most of the population of the galaxy have one poking in their ear. Thus, the Babel Fish has effectively removed all language barriers, and has consequently allowed so much more to be communicated; it has caused more, and bloodier wars than anything in the history of creation.
