U X B = Unexploded Bomb. How strange a world we live in, that requires that we have a term for such an evil device.
Another random thought: what if there is a planet somewhere in this universe that has intelligent life, and only two species of life... the eaters and the eaten. The eaten take their nourishment from the atmosphere and the eaters take their nourishment from the eaten. Our planet seems rich by comparison.
What strange thoughts I wake up to when I sleep the whole night through.
