Ready to feel old? Sabrina the Teenage Witch premiered on ABC's T.G.I.F. twenty years ago today!

Even Melissa Joan Hart, who starred on the show for seven seasons, said in a Nutrisystem press release that she "honestly can't believe it's been 20 years." The now 40-year-old actress has done a lot since Sabrina premiered back in 1996, but she still has nothing but fond memories from her time on the show.

"Sabrina was such a fun character," said Hart, now a married mother of three. "She was always full of surprises."
