I watched this show every Saturday morning growing up. Zack was a cool cat and it was a light and fluffy half hour. At least it was light and fluffy until Jessie Spano started doing drugs. No, it wasn't smack, it was the dreaded caffeine pills.
My favourite episode was probably the documentary style ep featuring The Zack Attack. Who will ever forget their big hit, Friends Forever?
And of course, the series had a memorable opening theme song and we all know the words by heart.
