Ben and Zane were rooting through the local landfill (like ya do) when they came across a giant robot that nobody had ever noticed before, somehow. They poked and prodded and fiddled with the knobs so much that when a woman from the future came to reclaim it, she couldn't pilot it any more. Now it's up to the Cartoncasters to control it by reviewing old cartoons. But that sounds like work, so maybe they'll just leave the TV on to Wrestlemania while they go out for some cheese steaks.
