On the right hand side, you'll find links to some highly recommended titles. I dare you (yes, you read that right, in fact I double dog dare you) to view the film entitled Perversion For Profit. It's an amazing expose of the evils of smut from the dark heart of McCarthy's America.
You'll find lots of classic classroom titles, including the popular Lunchroom Manners with Mr. Bungle, made famous by Pee Wee Herman.
