This is the most asinine idea I've ever heard. A spin-off with Cleveland as the central character? I can think of several characters for whom a spin-off would work.Let's see...Joe, Quagmire, Death, Bonnie, Loretta, Brian's gay cousin Jasper, Mayor West, Horace the bartender, the greased-up deaf guy, Paddy Tanager, the giant chicken, Peter's mom, the newscasters, Lois' sister, and Stewie's evil half-brother Bertram.
And that's just to name a few.
