Dustin Diamond, who played the lovable Screech on the most baffling teen show of all time, Saved By the Bell, is writing a tell-all book about his thirteen years on the show. (He's already parlayed his C-list fame into a C-list sex tape.) He'll detail the sex and drugs that went on behind the scenes with castmates—noted thespians such as Mario Lopez, Elizabeth Berkeley, and Tiffani Amber-Thiessen. It will be called Behind the Bell. It will have a ghostwriter. [via Vulture] To refresh your memory, one of Screech's greatest soliloquies after the jump.
