Jane Austen's P&P is quoted a bit. Or it's just variations of the first line, "It's widely known that every blahblah is in search of a blahblah."

Heeee~~ Pratchett FTW! My sister and I quote him to each other all the time! Unfortunately, this being America and my peers being all engineers or science majors, no one else I know has read his books. Woe.
