After 100 episodes covering everything from cicadas to NFTs, hosts Michael and Michael celebrate this milestone by diving into the surprisingly limited world of blimps. With only 25 active blimps worldwide and half of those actually flying, the duo explores how these "true marvels of technical achievement" have evolved from military surveillance tools to floating billboards. Along the way, they uncover the Goodyear blimp's $20 million upgrade from non-rigid to semi-rigid, Led Zeppelin's connection to Keith Moon's "lead balloon" joke, and why Michelin—yes, the tire company—started rating restaurants to sell more tires.
