Decoder Ring

McGruff the Crime Dog arrived on the scene at the dawn of the 1980s, just as a firehose of anti-drug PSAs was inundating the youth of America. These messages didn’t always work as intended—but they did work their way into the long term memories of the kids who heard them.
In the first of two episodes, originally released in 2022, we take a look at PSAs and their strange afterlife through the lens of a trench-coat wearing bloodhound and his bizarre, yet catchy anti-drug songs. We’ll talk to Dan Danger, Sherry Nemmers, Joseph Cappella, David Farber, Mike Hawes, and Robin Nelson to discover how the McGruff Smart Kids Album came to exist in the first place.
This episode was written by Willa Paskin. It was produced by Willa Paskin and Katie Shepherd. We had production help from Sam Kim. Editing by Jamie York and Derek John. Decoder Ring is produced by Max Freedman and Evan Chung, our supervising producer. Merritt Jacob is Senior Technical Director. Our intern is Phoebe Mulder.

The sun has always been a hot topic. For centuries, we’ve flip-flopped over whether our health depends on soaking up its rays—or shielding ourselves from them. The current conventional wisdom is clear: Avoid sunburns at all costs, using shade, hats, long sleeves, and the highest SPF sunscreen your drugstore has to offer.

But in a historical sense, that advice is pretty new. Not long ago, doctors told parents to slather babies in oil and let them roast in the afternoon sun. Tanning was once medically prescribed. Though we’ve lived under it for all of human history, we’ve never quite figured out how much sun is actually good for us. So where has the pendulum landed today? And why does it keep swinging in the first place?

In this episode of Decoder Ring, Willa talks to Rowan Jacobsen, author of the new book In Defense of Sunlight: The Surprising Science of Sun Exposure, who argues that our current guidelines have gone too far in emphasizing the risks of the sun. She also speaks with Catherine Cocks, the director of the Syracuse University Press and author of Tropical Whites: The Rise of the Tourist South in the Americas, about how race drove our cultural obsession with suntanning.

This episode was written by Willa Paskin and our supervising producer, Evan Chung, who also produced this episode. Decoder Ring is also produced by Max Freedman. Merritt Jacob is Senior Technical Director. Our intern is Phoebe Mulder.

Most of us use GPS—the Global Positioning System—on a daily basis: to find our location when we’re driving, running, shopping, dating, and so much more. But GPS is even more important, and more vulnerable, than you think.

In the last few years, GPS interference has been reported all over the world, from war zones to shipping routes to public squares. What was once the fanciful plot of a Bond movie—bad guy manipulates GPS to start World War III—is increasingly plausible. How did the world come to rely so heavily on such an unreliable system?

In this episode of Decoder Ring, host Willa Paskin talks to journalist Katherine Dunn, author of the new book Little Blue Dot: How GPS Shaped the Modern World. You’ll learn how GPS works, why it was created, how it became so ubiquitous, and why it’s now under attack. You’ll also hear from Dr. Todd Humphreys, an aerospace engineer who manipulated GPS to trick an $85 million superyacht into following his direction—for science, of course.

This episode was written and produced by Max Freedman. It was edited by Willa Paskin and Evan Chung, our supervising producer. Merritt Jacob is Senior Technical Director. Our intern is Phoebe Mulder.

It seems like the only time you hear about new statues these days is when something goes horribly wrong. Unfortunate bronze renditions of Lucille Ball, Cristiano Ronaldo, Dwayne Wade, and many others are always going viral, becoming a fixture of late-night shows and mocking comment sections. Is the internet too harsh a critic? Or is American statuary a total bust?
In this episode of Decoder Ring, host Willa Paskin talks to artist Atalanta Arden-Miller about what’s happened to one of the oldest artistic traditions in the world—why so many contemporary statues turn out off-center, off-kilter, and off-putting. The answer takes us from ancient Greece to Nazi Germany to North Korea.
This episode was written by Willa Paskin. It was produced by Max Freedman. It was edited by Josh Levin and Evan Chung, our supervising producer. Merritt Jacob is Senior Technical Director. Our intern is Phoebe Mulder.
Special thanks to the Works in Progress Podcast, where we first heard Atalanta talk about the dismal state of statuary today.

You know the Tootsie Shot. It’s that image that pops up all the time in movies set in a dense city: a really busy midtown street, everyone going somewhere—and smack in the middle of it all is the protagonist. You can find it in Working Girl, Midnight Cowboy, Wall Street, Heartburn, Elf, Bridget Jones’s Diary, The Devil Wears Prada, The Wolf of Wall Street, and so many more. But while it’s one of the most recognizable camera shots in all of film, it only amounts to a short, transitional moment, often in the middle of a montage, and sometimes lasting for a couple seconds. It is, after all, just someone walking down a crowded street. So why is it so sticky?
Some of the voices you’ll hear in this episode include James Sanders, author of Celluloid Skyline: New York and the Movies; cinematographer Adam Holender; producer Anna Wenger; assistant director Joe Reidy, author Christopher Bonanos, media and entertainment lawyer Sam Bayard, and location manager Mara Alcaly. Also thanks to Jason Bailey, Sam Levy, Glenn Kenny, Carlo Mirabella-Davis, J.D. Amato, David Sims, Bill Parker, Doug Brody, Sean Fennessey, and Jody Rosen.
