Another Backstage "Hey, It's That Guy!" (albeit a more obscure one): The show creator was Matthew Laurance, a one-time feature player on Saturday Night Live, during its critically abysmal sixth season. Laurence's only claims to fame on the show at that time was (a) his celebrity impression of mafioso Jimmy "The Weasel" Fratianno, and (b) he had a twin brother (Mitchell) who wrote for the show.
Subverted recently for Seasons 2,3 and 4. The first four seasons are now avaliable to stream on Hulu. Played straight with most of season 5, as only the first three episodes are on Hulu.
What Could Have Been: In 1995, a spin-off called Clarissa Now was pitched to CBS. It would have shown Clarissa as a college student in New York, working as an intern for a newspaper.
Interestingly, that was almost the exact same career path that Melissa Joan Hart's next character, Sabrina, did follow after high school. This has led to more than a few people joking that they didn't know it was two separate shows, and just assumed that Clarissa woke up and discovered she was a witch.
