Episode 17 of "Sabrina, the teenage witch"
s01e17 First Kiss

A Valentine's Day episode shows that while dating is tough when you're a teenager, it's even tougher when you're a teenage witch. Just as Sabrina and Harvey are about to share their first kiss, Salem desperately interrupts them. Sabrina's cat isn't trying to be a pest, and no, he's not jealous... rather, the feline knows that a kiss from Sabrina will turn Harvey -- or any boy for that matter -- into a frog. In order to reverse the tragic spell, Sabrina must pass the Witches' Council's "Test of True Love" to prove that her feelings for Harvey are genuine... and Hilda takes the opportunity to demonstrate the depth of her attachment to Drell (rather less successfully).
