Bill Nye Quote

The comet is a kind of astronomical parody on the planet. Comets look some like planets, but they are thinner and do not hurt so hard when they hit anybody as a planet does. The comet was so called because it had hair on it, I believe, but late years the bald-headed comet is giving just as good satisfaction everywhere.
