The actress cleverly combined Throwback Thursday with a special birthday message for actor Jason Zimbler, who played Clarissa's bratty sibling Ferguson Darling in the hit Classic Nickelodeon series, on her official Instagram profile page, @MelissaJoanHart.
Alongside a picture of them in the show, she wrote: "Happy birthday to the most obnoxious little brother I ever had the pleasure of working with. Happy birthday Jason! #fergface #ferguson #YoungRepublicans #Clarissa #ClarissaExplainsItAll."
Since Melissa posted the photo, thousands of fans have liked the picture and left comments reminiscing on just how great the series was!
"Clarissa Explains It All" aired on Nickelodeon in the mid-nineties and followed the teen as she discussed school, boys and her annoying brother, Ferguson.
Following "Clarissa Explains It All", Zimbler graduated from Notre Dame in 1998, started his own theater company in 2007, and has worked for HBO as a software designer since 2009.
Melissa Joan Hart went on to star in Nickelodeon UK favourite "Sabrina the Teenage Witch", and the ABC Family sitcom "Melissa & Joey", alongside Joey Lawrence ("Blossom").
