I've read many of those. I think Virginia Woolf's line from "Orlando" is awesome. Gabriel Garcia Marquez's line is also awesome.
But my all-time fav opening line (and one of my fav novels ever)
"Since the days of Adam, there has been hardly a mischief done in this
world but a woman has been at the bottom of it." William Makepeace Thackeray "Barry Lyndon"
