In the first part of this special two-part series, the guys explore the origin story of modern roller coasters, from the old days of "Russian Mountains" to an amusement arms race that continues today: the ongoing quest to build the biggest, highest, fastest rides on the planet.

In the mid-19th century, London was literally filling with corpses. When the city was in the grips of a cholera epidemic, the already-overfilled cemetaries couldn't handle the extra bodies. So when there's literally no room in the soil for another dead body, what's a city to do? To the creators of the London Necropolis Railway, the answer was simple -- build a train for the dead. Tune in to learn some grisly, ridiculous history with Ben and Noel. See omnystudio.com/listener for privacy information.

In a burst of meta-humor, the Encyclopædia Britannica defines encyclopædia as "reference work that contains information on all branches of knowledge or that treats a particular branch of knowledge in a comprehensive manner." It's high praise -- but if there's any single book that's earned the right to describe itself this way, it's this one.

The Principality of Liechtenstein is a small, landlocked country out in the alpines -- and while it's a tiny nation, it has an enormous depth of history.

Look! Up in the sky! It's a bird. It's a plane. It's... "definitely not Superman." At least, that's what Fawcett Comics told the courts, beginning a multigenerational, multiversal saga of strangeness that continues in the modern day.
