Hollywood loves the spin-off. Ideally, it’s a way of turning one success into two or three (or four or more) successes. Happy Days alone begat Laverne & Shirley, Mork & Mindy, and, Joanie Loves Chachi. But not every great spin-off idea becomes a reality, as Mental Floss’ Mike Rugnetta explains in an episode of The List Show called “29 Spin-Offs That Almost Happened.” Cynics might think of this as “29 Times The American Viewing Public Dodged A Bullet,” but there are some intriguing could-have-been shows in here, too. Friends fanatics, for instance, might have genuinely enjoyed Girlfriends, a proposed series built around Lisa Kudrow’s Phoebe Buffay character. Archer star Aisha Tyler would have co-starred in that circa-2003 project. The Simpsons, meanwhile, could have spawned at least two adjunct shows: a live action series devoted to Krusty The Clown and an animated one about what the other residents of Springfield are doing when they’re not serving as supporting characters in the lives of Homer, Bart, et al.
