i was born on the shores of the Chesapeake Bay but Maryland and Virginia have faded away
and I keep thinking tomorrow is coming today so I am endlessly waiting
and the comet is coming between me and the girl who could make it all clean.

halley's comet (commonly pronounced /ˈhæli/, rhyming with valley) is the best-known of the short-period comets, and is visible from earth every 75–76 years. halley is the only short-period comet that is clearly visible to the naked eye from earth, and thus the only naked-eye comet that might appear twice in a human lifetime.
