The Most Frequently Banned Book of 2012: Captain Underpants?

Yep. Self-appointed guardians of morality aren't trying to protect our kids from To Kill a Mockingbird nearly as often as the Captain Underpants books, which to be fair have "underpants" in their title. That's the shocking revelation from this year's Banned Books Week.

The American Library Association released its list of the most challenged books of 2012, for Banned Books Week, and some popular choices from previous years were nowhere to be seen. Like The Hunger Games. And Brave New World. Or Twilight, for that matter. You can read the top 10 most challenged books of each year since 2000 right here.

Want to be even more depressed? Here's a list of just the classic books that have been challenged or banned, including Vonnegut, Orwell, Huxley, and Tolkien.

There's an extended "shortlist" of books that were challenged in 2012-2013 [PDF] and it includes basically every book you love, from Margaret Atwood's The Handmaid's Tale to M.T. Anderson's Feed to Alan Moore's Neonomicon to Daniel H. Wilson's Robopocalypse. Every book has something that upsets somebody enough to call for it to be removed from shelves.
