What makes the world’s first documented bar joke funny? No one knows.

In a tweet that garnered thousands of responses in March, the Twitter account @DepthsOfWiki posted about a 4,000-year-old proverb written on a clay tablet. The line, which experts believe is a joke from the ancient civilization of Sumer, starts with the set-up, “A dog walks into a tavern.” But the punchline has left scholars and online commenters scratching their heads. The joke’s meaning has been lost, and finding it could reveal something unique about early human civilization.

In this episode, the first of two parts, Endless Thread journeys back in time, attempting to deconstruct the origins of humor and explain an unexplainable joke from the forgotten tablets of the past.

You might not think about caves in the same breath as you do the deep ocean or outer space, but you probably should. There are approximately 70,000 caves in the United States alone, but the vast majority are inaccessible to the public. That means rare, delicate ecosystems have developed for tens of thousands of years in complete isolation from human contact. That is, until cavers travel deep underground through impossibly small spaces to find them. Join the Endless Thread team as we dive into the claustrophobia-inducing world of caving.

Reddit's Auntie Network, an online community "dedicated to providing information and resources to those in need of abortion services," has been inundated with new members since the Supreme Court's decision to overturn Roe v. Wade was leaked in early May. Community members can offer rides, lodging, and emotional support for anyone seeking an abortion — especially when crossing state lines.

In today’s episode, we hear from two moderators of Auntie Network, as well as the executive directors of the Blue Ridge Abortion Fund in Virginia and the Kentucky Health Justice Network, about how abortion rights advocates — online and off — can work together in a post-Roe America.

Imagine if an explosion in California was so loud that it could be heard in New York City. This is the story of a real event that was just as loud — the loudest sound ever recorded in human history.

This sound ripped across oceans in 1883, reaching people 3,000 miles away. Infrasonic pressure waves circled the globe four times. News of its destruction traveled through the early internet, the telegraph system, and altered the course of scientific history.

In this episode of Endless Thread, we recreate this magnum opus — a hotly debated darling of Reddit — with the help of scholars and infrasonic scientists.
