McSweeney's Internet Tendency: Dispatches from a Public Librarian
Link from Librarian.net (of course!). This guy is funny. Evidently a reference librarian; He calls Casanova the greatest librarian that ever lived, and this is why...
"In truth, Casanova didn't really like being a librarian and didn't contribute anything to the profession. Still, he is the only librarian to have Heath Ledger play him in a movie, which has to count for something."
