<begin quote> One sperm arrives before the others. It penetrates the egg, forms a lump on it's surface, the cell wall now thickens to prevent other sperm From entering. Within the now-fertilized egg, changes take place... And ten million kryptonian sperm arrive slightly late. Were they human sperm, they would be out of luck. But these tiny blind things are more powerful than a locomotive. A thickened cell wall won't stop them. They will *all* enter the egg, obliterating it entirely in an orgy of microscopic gang rape. So much for artificial insemination. <end quote> Heh. -Max Wilson -- Be pretty if you are, Be witty if you can, But be cheerful if it kills you.
