Jane Fonda’s Workout, Part 2: Hanoi Jane’s VHS Revolution (Encore) Sep 10, 2025

Show notes

In part two of our special two-part episode, we return to the 1982 VHS tape that created the at-home video industry: Jane Fonda’s Workout. On this episode, originally released in 2020, we deconstruct the tape itself, how it was made, and why anyone thought it was a good idea in the first place. Then we’ll explore how it was possible for an extremely polarizing political activist, despised by some for her activism during the Vietnam War, to become America’s premier exercise guru. It’s a story that involves one enterprising home video visionary, dozens of ridiculous celebrity workout tapes, Tricky Dick Nixon, and one very full life.

Some of the voices you’ll hear on this episode include Jane Fonda; Court Shannon, former Karl Video employee; and Mary Hershberger, author of Jane Fonda’s War.

This episode was written by Willa Paskin. It was edited and produced by Benjamin Frisch. We had research assistance from Cleo Levin. Decoder Ring is produced by Katie Shepherd, Max Freedman, and Evan Chung, our supervising producer. Merritt Jacob is Senior Technical Director.

Jane Fonda’s Workout, Part 1: Jane and Leni (Encore) Aug 27, 2025

Show notes

In 1982, the Jane Fonda Workout became the best-selling home video of all time. Over decades, it and its 22 follow ups would spawn a fitness empire, sell more than 17 million copies, and transform Fonda into a leg-warmer-clad exercise guru. And 40 years after its initial release, when the COVID pandemic hit, the workout had a moment yet again. People began doing it alone and on Zoom, tweeting about it, writing about it. So when Jane Fonda agreed to talk to us, we set out to do an episode about it—but it did not go as planned.

On Part 1 of a special two-part Decoder Ring, originally released in 2020, we explore the decades-long relationship of Jane Fonda and Leni Cazden, a fraught friendship that birthed the VHS workout that changed the world. It’s a story of creation, fame, forgiveness, trauma, betrayal, survival, politics, and exercise. You’ll hear from Jane Fonda and Leni Cazden, the brain behind the workout, and Shelly McKenzie, author of Getting Physical: The Rise of Fitness Culture in America.

In two weeks we’ll return with Part 2: the nitty gritty story of the bestselling VHS tape of all time.

How to Hunt a Mammoth, and Other Experiments in Archaeology Aug 13, 2025

Show notes

Experimental archeology is, simply put, archeology that involves running experiments. Where traditional archaeologists may study, research, analyze, and theorize about how artifacts were made or used, experimental archaeologists actually try to recreate, test, and use them to see what they can learn. In doing so, they have given the field a whole new way to glean clues and get insights into the lives of our ancestors.

Sam Kean is the author of a new book all about experimental archaeology called Dinner with King Tut. With help from him and a few archaeologists, we dig into a number of puzzles that experimental archaeology has helped solve—conundrums involving ancient megafauna, bizarre cookware, and deep sea voyages.

In this episode, you’ll hear from archaeologists Susan Kaplan of Bowdoin College and Karen Harry of University of Nevada, Las Vegas, and Native Hawaiian activist and storyteller Nāʻālehu Anthony.

To learn more about the story of Hokule’a and its first navigator, Mau Piailug, watch Nāʻālehu Anthony’s 2010 documentary, Papa Mau: The Wayfinder, as well as The Navigators: Pathfinders of the Pacific.

This episode was produced by Katie Shepherd and Max Freedman. Decoder Ring is also produced by Willa Paskin and Evan Chung, our supervising producer. Merritt Jacob is Senior Technical Director. We had mixing help from Kevin Bendis.

The Bad-Mouthing of British Teeth Jul 30, 2025

Show notes

From The Simpsons’ Big Book of British Smiles to Austin Powers’ ochre-tinged grin, American culture can’t stop bad-mouthing English teeth. But why? Are they worse than any other nation’s? June Thomas drills down into the origins of the stereotype, and discovers that the different approaches to dentistry on each side of the Atlantic have a lot to say about our national values.

In this episode, you’ll hear from historians Mimi Goodall, Mathew Thomson, and Alyssa Picard, author of Making the American Mouth; and from professor of dental public health Richard Watt.

This episode was written by June Thomas and edited and produced by Evan Chung, Decoder Ring’s supervising producer. Our show is also produced by Willa Paskin, Katie Shepherd, and Max Freedman. Merritt Jacob is Senior Technical Director.

Mailbag: Drug Names, Cow Abductions, and the “Ass-Intensifier” Jul 16, 2025

Show notes

In this episode we’re opening our mailbag to answer three fascinating questions from our listeners. How did “ass,” a word for donkeys and butts, become what linguists call an “intensifier” for just about everything? How do pharmaceuticals get their wacky names? And why do we all seem to think that aliens from outer space would travel to Earth just to kidnap our cows?

In this episode, you’ll hear from linguistics professor Nicole Holliday, historians Greg Eghigian and Mike Goleman, and professional “namer” Laurel Sutton.

This episode of Decoder Ring was produced by Willa Paskin, Max Freedman, and Katie Shepherd. Our supervising producer is Evan Chung. Merritt Jacob is Slate’s Technical Director.

Introducing The Sporkful | Is Your Recipe Lying To You? Jul 09, 2025

Show notes

If you look at any list of best-selling cookbooks, certain words come up over and over again: quick, easy, fast, effortless. But is it actually possible to deliver deliciousness in no time? Or are these recipes too good to be true? This week, The Sporkful talks with intrepid journalist Tom Scocca, who exposed the dirty secret about caramelized onions; recipe-writing legend Christopher Kimball; and food writer (and mom) Elizabeth Dunn, who’s sick of feeling bad when a recipe turns out to be harder than she expected. And we ask: Why do recipes that look simple on paper turn out to be very different once you get into the kitchen?

Tom Scocca is the editor of Indiginity, and you can read his Slate story about caramelizing onions here. Christopher Kimball is the founder of Christopher Kimball’s Milk Street. Elizabeth Dunn co-writes the newsletter Consumed.

The White Noise Boom Jul 02, 2025

Show notes

White noise has a very precise technical definition, but people use the term loosely, to describe all sorts of washes of sound—synthetic hums, or natural sounds like a rainstorm or crashing waves—that can be used to mask other sounds. Twenty years ago, if you’d told someone white noise was a regular part of your life, they would have found that unusual. Nowadays, it’s likely they use it themselves or know someone who does. The global white noise business is valued at $1.3 billion; TikTok is full of people trumpeting its powers; and Spotify users alone listen to three million hours of it daily. Far more of these sounds already exist than any one person could need—or use. And yet, more keep coming.

Looking out at this uncanny ocean of seemingly indistinguishable noises, we wanted to see if it was possible to put a human face on it; to understand why there is so much of it, and what motivates the people trying to soothe our desperate ears with sounds you're not really supposed to hear.

In this episode, you’ll hear from Elan Ullendorff, who writes the illuminating Substack Escape the Algorithm; Stéphane Pigeon, founder of myNoise; Brandon Reed, who runs Dwellspring; and Mack Hagood, author of Hush: Media and Sonic Self-Control and host of the podcast Phantom Power.

We’d also like to thank Dan Berlau, Sarah Anderson, and Ashley Carman.

This episode was written by Katie Shepherd, Evan Chung, and Willa Paskin. It was produced by Katie Shepherd. We produce Decoder Ring with Max Freedman, and Evan is also our supervising producer. Merritt Jacob is Senior Technical Director.

The Boston Cinematic Universe Jun 18, 2025

Show notes

This episode is a first for Decoder Ring: a live show, recorded at the WBUR Festival in Boston, Massachusetts. Given the setting, we decided to take on a Boston-based cultural mystery: namely, the “Boston movie.” Beginning in the late 1990s and early 2000s, Hollywood has churned out a whole cycle of films drenched in Beantown’s particularities, crimes, crops, class conflicts, and accents, from The Departed to The Town. Why does a city smaller than El Paso or Jacksonville loom so large in the cinematic imagination? Why does Boston have a movie subgenre all its own? What makes a Boston movie a Boston movie?

With the help of three guests—film critic Ty Burr; Lisa Simmons, founder of the Roxbury International Film Festival; and Boston University linguist Danny Erker—we look closely at the history and heyday of the Boston movie: how The Friends of Eddie Coyle set the template, Good Will Hunting shoved the door wide open, and Mystic River ushered in an imperial phase. We discuss the importance of race and class to the Boston movie and the city itself, the role of homegrown movie stars like Ben Affleck and Mark Wahlberg, and, of course, the best and worst of Boston accents on film.

This episode of Decoder Ring was produced by Willa Paskin and Max Freedman. Our team also includes Katie Shepherd and supervising producer Evan Chung. Merritt Jacob is Slate’s Technical Director.

The Laff Box (Encore) Jun 04, 2025

Show notes

Decoder Ring is marking its 100th episode this year. To celebrate, we’re revisiting our very first episode from 2018, which asks: What happened to the laugh track? For nearly five decades, the laugh track was ubiquitous, but beginning in the early 2000s, it fell out of sitcom fashion. What happened? How did we get from The Beverly Hillbillies to 30 Rock? In this episode we meet the man who created the laugh track, which originated as a homemade piece of technology, and trace that technology’s fall and the rise of a more modern idea about humor. With the help of historians, laugh track obsessives, the showrunners of One Day at a Time and the director of Sports Night, this episode asks if the laugh track was about something bigger than laughter.

You can read more in Willa’s article “The Man Who Perfected the Laugh Track” in Slate.

The Glaring Problem with Headlights May 21, 2025

Show notes

Something seems to have happened to car headlights. In the last few years, many people have become convinced that they are much brighter than they used to be—and it’s driving them to the point of rage. Headlight glare is now Americans’ number one complaint on the road. The story of how and why we got here is illuminating and confounding. It’s what happens when an incredible technological breakthrough meets market forces, regulatory failure, and human foibles.

So if you feel like everyone’s driving around with their high beams on all the time, it’s not your imagination. What once seemed like an obscure technical concern has gone mainstream. But can the movement to reduce glare actually do something about the problem?

In this episode, you’ll hear from Nate Rogers, who wrote about the “headlight brightness wars” for The Ringer; Daniel Stern, automotive lighting expert and editor of Driving Vision News; and Paul Gatto, moderator of r/fuckyourheadlights.

This episode of Decoder Ring was written by Willa Paskin and Olivia Briley, and produced by Olivia Briley and Max Freedman. Our team also includes Katie Shepherd and supervising producer Evan Chung. Merritt Jacob is our Senior Technical Director.
