In February of 1908, racing teams from multiple nations assembled for an unusual and ambitious race -- they planned to drive from Times Square across the planet to France. These were the early days of the automobile, and success was anything but guaranteed. In today's special 3D episode, Ben and Noel trace the highs (and, mostly, lows) of the men who vied for what they saw as the ultimate prize: A 1,400-pound trophy and lifelon...

It appears many eras in history have their own version of sneakerheads. In 15th-century Europe, nobles and commoners alike went absolutely nuts for a type of pointy shoe called the Crakow -- and people desperately wanted the longest, pointiest shoes possible. In this episode, Ben and special guest Matt Frederick, co-creator of Stuff They Don't Want You To Know, explore the origin of the Crakow (and how, eventually, governments ...

As the British military brainstormed ways to break the German-built Atlantic Wall during World War II, desperation drove them to unorthodox ideas -- one of those, the Great Panjandrum, was a literal rocket-powered, rolling bomb. Tune in to learn how the Panjandrum came to be, what went wrong with it, and how amazing it is that no one actually died during testing.

Times were tough during the Great Depression. Economic unrest, massive migration and falling crops left many people struggling to survive -- even the simple task of finding food from one day to the next became increasingly challenging. Amid this chaos Dr. T. W. Stallings saw an opportunity: If he could convince the good people of Oklahoma to start eating crows the way they ate other birds like ducks or chickens, he could save some ...

As the pineapple craze swept through Europe's upper class, aristocrats worked tirelessly to grow their own pineapples. This was no small feat, since pineapples aren't suited to the European climate. Still, some clever inventors and gardeners figured it out -- and, along the way, non-aristocrats also got into the trend. Since most people couldn't afford a pineapple, they did the next best thing and rented them as a displ...

Today, pineapples are a common (and delicious) produce item found in grocery stores and markets across the world -- but not too many centuries ago, a single pineapple could cost the equivalent of over $8,000. In the first part of this two-part episode, the guys delve into the bizarre story of Europe's pineapple mania, attempting to discover just what made this fruit so insanely popular... and why they're so insanely cheap t...

As New Englanders woke on the morning of May 19th, 1780, they realized something was... off. The sunrise looked oddly colored and dim. As the day wore on, the sky grew increasingly dark. Soon, it appeared midnight had come early. Animals and humans alike panicked -- cows ran to their stalls, people flocked to churches and taverns, many certain the end of the world was upon them. Eventually, things returned to normal, but in the cen...

As the French and Indian War escalated, the residents of Windham, Connecticut lived in constant fear of possible attacks, crop-ruining weather, disease and more. One late night in the summer of 1754, a loud, continual noise roused the entire town as people feared they may be under siege. It wasn't until near dawn that the noises died down, and a small scouting party discovered the culprits of the cacophony -- a massive populati...

Thousands of years before the current day, ancient civilizations accurately predicted both lunar and solar eclipses. They often believed these events were spiritual omens. When an eclipse came at an inauspicious time, multiple priestly classes scrambled to find a substitute king. In the interest of preserving society, these substitute kings would reign during an eclipse, only to be swiftly murdered afterward. Ben defends early huma...

As the small town of Mattoon captured national attention during the reign of the Mad Gasser, the investigation took a turn. Authorities were baffled by the deluge of reports -- and their inability to find any physical evidence other than a soiled rag at a doorstep. As researchers and historians looked back on the events, they became increasingly convinced the was a different culprit behind the panic... and though the story was a ga...

As wartime fears peaked across the US during World War II, people throughout the nation were overwhelmed with fears of invading Nazis, secret biological weapons and more. For the residents of Mattoon, Illinois, these fears took a brief back seat to a new neighborhood menace -- a Mad Gasser who would sneak beside people's windows and pipe in a paralytic gas for reasons no one could understand. But who was this Mad Gasser? What o...

For thousands of years people across the planet lived in fear of leprosy (now known as ‘Hansen's Disease). In many cases, people infected with the disease, or even just suspected of having it, were carted off to isolated colonies where they would be doomed to live the rest of their lives without any access to the outside world. These colonies became their own active communities -- there were blacksmiths, traders, cooks, merchan...

Back in the 1930s, the residents of Wyoming, Montana and South Dakota felt the federal government— and the state legislatures— ignored them. They felt unheard, unheeded and, most importantly, moved to find solutions of their own. In this episode, Ben and Noel return to the story of Absaroka to ask: Was this meant to be the 49th state, or was it a publicity stunt?

George Parrott was a career outlaw -- a known thief, murderer and would-be train robber. When justice finally caught up with him and his game, he was destined for the hangman's noose. Yet George's demise was only the beginning of a bizarre posthumous tale. Tune in to learn why it's technically possible, even today, to walk in Big Nose George's shoes (and not, perhaps, in the way you might assume).

In the second part of this two-part episode, Ben, Noel and special guest Gabe Luzier drill down into the nuts and bolts of flea circuses -- how did they actually work? Is it true that some flea circuses did not, in fact, have fleas? Is there any way to see a real flea circus in the modern day? Tune in to learn more about one of history's strangest novelty performances.

Fleas -- they're one of the only animals Ben actually doesn't like! Yet, once upon a time, these bloodsucking nuisances were star performers in novelty acts across Europe and, later, North America. But what were they, exactly? Can you really train fleas to do tricks and play instruments? Who even came up with this weird idea? In this episode, the guys welcome special guest and researcher extraordinaire Gabe Luzier to dive i...
