Episode notes

While Carrie is out of town, Ross and his cohorts at the Independent Investigations Group set up a test to see if the Earth is flat, or a lumpy, bumpy globe. And they invite their old friend Mark Sargent, and a cadre of flat earthers to join them. Arriving at the Salton Sea with some PVC pipe, balloons, and a magical camera that recovers ships lost on the horizon, these globeheads and flatties devise a fair and simple test of the Earth’s shape. We’ll let you guess how that turns out.
