There's no doubt that How-To books serve a great purpose. They guide us through life with the essential tips we need - like how to build your own coffin or how to date white women. You know, everyday stuff that we all should know, but require a little extra direction. Okay, some may be a tad unorthodox, but those are the ones we love. While these may not have been flying off the shelves, we're pretty grateful they exist.
