Dustin Diamond just keeps going and going exposing it all. This time he's writing a "tell-all" book about Saved By The Bell, Behind the Bell. The book is said to have "sexual escapades among cast members, drug use, and hardcore partying." It's really easy to rat other people out when your not invited to join the party. But whatever pays the bills right Dustin? Hopefully he'll make enough money off this book that he won't have to purposely gain weight to go on Celebrity Fit Club season 15, 16, 17...
