The challenge is to find an example of a TV show that is a spinoff of a spinoff of the original TV show. I can’t think of one that exists to give as an example, but it’d be like if Niles spun off his own TV sitcom from Frasier, which itself was a spinoff of Cheers.
To be clear, it’s not a show (like Happy Days) that has numerous spinoffs from it. There’s lots of examples of that. But has there ever been a show that’s spun-off a show that itself was a spin-off of an original show.
I thought I might have found one: The original was All In The Family… The Jeffersons was spun off that… Then I thought there was a short-lived sitcom spun off of the Marla Gibbs maid character ‘Florence Johnston’, but a trip through IMDB shows that to be a negative (although, Marla Gibbs’ Florence Henderson did, apparently, show up on one episode of Fresh Prince).
I cannot believe that there hasn’t been a show that’s a spinoff of a spinoff of an original show. I’ll accept a tv character starring in three separate tv series, but preferably it’d be a separate character spinning off from the spinoff. For instance, if Niles got his own show spun off from Frasier, which was a spinoff from Cheers.
