Thanks Superdude103194, great clip. The AH-HA moment is always memorable. Hard to pin mine down, in my day Saturday mornings were filled with the great Republic Serials from the 30’s and 40’s along with cartoons like Scooby-Doo, Underdog, and Rocky and Bullwinkle.
We were inundated with images like your Rugrats clip, but it was probably the Republic Serials, live action shorts originally shown in movie theaters before the feature film and always ending with a cliffhanger. Most often it was the hero, or his love interest, on a conveyor slowly moving toward some horrible fate. They would be rescued at the beginning of the next installment, capture the villain, and after a quick embrace start a new adventure.
