File this under: the greatest thing you'll see all day. Eight years after Melissa Joan Hart said goodbye to Sabrina Spellman and her witchy ways, the former 'Sabrina the Teenage Witch' star spoofed her popular spellbinding role in a new video for Funny Or Die -- starring her former co-star, Salem the cat.

In the hilarious clip, the actress reunites with Salem (voiced by Nick Bakay) for lunch to catch up. But, then Salem -- always the bad influence -- convinces Hart to embrace her dormant inner-Sabrina and perform a little magic ... and that when Melissa loses it. She morphs into a power-hungry witch, attacking the restaurant's guests with "magic!"

And when a little boy tries to combat Melissa's witchy ways with the 'Harry Potter' defense spell, "Expelliarmus," the actress disarms him with her own clever counter-attack.

Fashion icon. Sister. Best friend. Daughter. Explainer of it all. Nickelodeon's Clarissa was every one of those things. When the Melissa Joan Hart–fronted 'Clarissa Explains It All' ended in 1994, the title character went off into sunset to become a journalist in New York City.

But that wasn't exactly the end of Clarissa -- Nickelodeon and CBS planned 'Clarissa Now,' a new show that would have seen Hart play the title character as she interned at a busy New York newspaper. The pilot aired on Nickelodeon, but never made it to series. Thanks to the Internet, the show was uploaded to YouTube and made the rounds last week.

TV Squad caught up with Clarissa herself, Melissa Joan Hart, at the ABC Family Upfront where she reflected on what happened to 'Clarissa Now.'

"I thought it was a fun show, although I don't remember it very well," Hart said. "But it skewed a lot older because it was a different time. CBS was very much an older-demographic network back then.

"They tried to age the show up a little bit, but the thing is, the 'Clarissa' audience was so young and hip. I just think it didn't work. It's not what people wanted to see."

For those still hankering for even more 'Clarissa,' TeenNick will air the original series starting in the fall as part of a new programming block called 'The '90s Are All That.' Watch the full 'Clarissa Now' pilot after the jump.

Bust out your orange soda and touch up your mermaid tattoo, children of the '90s: Nickelodeon has finally gotten hip to the fact that the nostalgia factor of its revered shows of the early-to-mid-'90s has reached critical mass.

In response, TeenNick has announced that it will start airing those beloved series from midnight to 2AM this fall in a new programing block called 'The '90s Are All That,' Entertainment Weekly reports. Hey, cool!

Among the high-quality shows included are 'Clarissa Explains It All,' 'The Adventures of Pete & Pete,' 'All That,' 'Kenan & Kel' and 'The Amanda Show.'

"At the time, we were completely devoted to that audience ages 9, 10 and 11," TeenNick general manager and senior vice president Keith Dawkins told Entertainment Weekly. "It was ground-breaking and for the young viewers, a powerful and pivotal time in their lives. Those kids who are now 22, 23 and 24 want to bring that back."

As a kid, my parents were totally cool with my television viewing habits, as long as it never became excessive or kept my face from being kissed by the light of day every once in a while. Not that they had anything to be worried about, of course, considering that all I was watching was Nickelodeon.

While my fellow prepubescents were slowly but surely migrating to more grown-up programming on MTV (and Playboy, if you had a cable box), I spent the bulk of my time between 1992 and 1996 fully devoted to Roundhouse, a 30-minute sketch show sandwiched between the more popular Clarissa Explains It All and Are You Afraid Of The Dark? on SNICK, Nickelodeon's Saturday night programming block.
