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.

The first documented bar joke was copied onto a clay tablet 4,000 years ago in the ancient language of Sumerian. Scholars have translated it, but the meaning remains lost. After the Twitter account @DepthsOfWiki posted the joke in March, thousands of people attempted to decipher it to no avail.

Yet, as cryptic as the bar joke may be, it offers clues into humor’s role in human civilizations and raises questions about when humor — and its sibling laughter — first emerged.

In this episode, the second of two parts, Endless Thread continues its journey attempting to deconstruct the beginnings of humor and explain an unexplainable joke from the forgotten tablets of the past.

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.

In this summer-y episode of Endless Thread, Ben and Amory take a leap of faith (or do they?) to the depths of an upstate New York swimming hole with a legend surrounding it that's almost as shadowy as exact it's location.

“Which one of you freaks hijacked the south Boston green space google maps for your furry photo shoot?”

Earlier this year, a Redditor was trying to find the person who uploaded pictures of himself posing in a dog mask and rubber suit to this location in Google Maps.

But he's no furry. He's a pup. There's a difference, we learned, after speaking to the subject of these photos.

Take a walk on the kinky side in this episode that explores the origins of puppy play and how the internet and the pandemic shaped the pup community.

Reddit is restricting the use of third-party apps. More than 8,000 subreddit communities shut down in protest — including r/Blind, which says the change will drastically reduce accessibility.

In this special episode, co-host Ben Brock Johnson speaks with two moderators of r/Blind about their concerns.

Since the creation of deepfakes in 2017, the AI-powered technology that swaps faces into videos has become commonplace, particularly in pornography.

Using someone's image without their consent to create porn can have damaging effects, emotionally and physically. But no federal law criminalizes the creation or sharing of non-consensual deepfake porn in the United States.

Endless Thread co-hosts Amory Sivertson and Ben Brock Johnson speak with producer Dean Russell about deepfake law and the movement for change.

Since the pandemic, foraging has exploded in popularity. Younger generations are embracing (or romanticizing) the great outdoors with trends like #cottagecore and #vanlife. But our Endless Thread team decided to learn the do's and don'ts of foraging from someone who learned how to forage since childhood — not as a trend, but as a way of life.

r/randonauts is a fast-growing community of Redditors who use random, quantum-generated coordinates to go on real-life adventures. But what happens when those random coordinates lead you straight to a grisly crime scene? We revisit an episode that took Ben and Amory on their own random adventures back in 2020.

This week on Endless Thread, host Ben Brock Johnson and producer Grace Tatter look at a meme inspired by supermodel Bella Hadid's call to compliment each other on attributes other than physical appearance, and ask what really makes for an authentic compliment.
