When I was a kid, the only kids' show I watched was Sesame Street.
Almost 15+ years later, the only thing that I remember vividly and still love was the crayon-making.
I was never able to re-watch it again because I am pretty sure I watched it on Saturday morning (I don't know if there's still Saturday Morning Cartoons anymore.. but back then, it was on every weekend).

I LOVE YOUTUBE.
