"The Babel Fish," said The Hitchhiker's Guide To The Galaxy quietly, "is small, yellow and leechlike, and quite possibly the oddest thing in the universe." If you stick a Babel Fish in your ear, you can instantly understand anything said to you in any form of language. The reason for this, (though reason is out to lunch right now) is that the Babel Fish feeds on brainwave energy from those around it. It absorbs unconscious mental frequencies from said brainwave energy, to nourish itself with. Then it excretes a telepathic matrix into the mind of its host, formed by combining unconscious mental frequencies with the nerve signals of the brains speech centers. Some thinkers use its existence to disprove that of God.
