Stuff You Should Know
Stuff You Should Know, often abbreviated as SYSK, is a podcast and video series originally published by HowStuffWorks and hosted by Josh Clark and Charles W. "Chuck" Bryant. The podcast, which launched in 2008, educates listeners on a wide variety of topics, often using popular culture as a reference.
From its launch in 2008 through 2025, the podcast consistently appeared in the Top 10 rankings on Apple Podcasts and Spotify, indicating that it's one of the most popular podcasts in the world. On October 3, 2018, the podcast started releasing additional short episodes titled Short Stuff, where they cover topics that don't warrant the length of a full episode. A number of other types of media, including a TV show and books, have been spun off by the podcast.
Hosts
Stuff You Should Know is hosted by two podcasters who first met while working as senior editors at HowStuffWorks.com, Josh Clark and Charles Wayne "Chuck" Bryant.Clark was a host of the show since the beginning, and before Bryant took over the co-hosting duties Clark was joined by several other editors. The chemistry between the two was immediately apparent, and Bryant became a permanent co-host. Bryant started working at HowStuffWorks about a month after Clark. They had desks kitty-corner across from each other and would often pop up to share their research. They became good friends within a week.
Josh M. Clark
Josh Malcolm Clark was born July 15, 1976. He grew up in Toledo, Ohio and was raised Catholic, attending a Catholic school. He studied at the University of Georgia, but left with six classes left to start his newspaper.He moved to Marietta, Georgia as a teenager. Clark's father's name is Mal, an HVAC engineer. He had a sister named Karen, who died in 1992 in a car accident when Josh was 16 years old, and two brothers-in-law, one of whom is also named Josh. In 2010 Clark lived with his then-girlfriend Umi in midtown Atlanta; he proposed on August 13, 2011 and the couple has since married. The couple have a dog, Momo.
He is a former smoker, drinks a lot of coffee, and is an amateur mixologist. His hero is Muhammad Yunus. His favorite books include 1491 and 1493 by Charles C. Mann which he frequently quotes and/or references in the SYSK podcast. Josh is also a fan of The Simpsons, Firefly, Dollywood, Quentin Tarantino and shares an affinity with his cohost Bryant for the band Pavement.
He attended Sprayberry High School and studied history and anthropology at the University of Georgia. As a youth interested in the paranormal, he wanted to study parapsychology at Duke University. Also as a child, he was an avid reader of Uncle John's Bathroom Reader, as mentioned in many podcasts, and he jokingly cites Uncle John's Bathroom Reader as the source of the majority of his knowledge. This admiration was eventually reciprocated when UJBR mentioned SYSK on their website and had one of their employees feature as a guest on SYSK's Barbie doll podcast.
After college he pursued a career in journalism, working as "a cub reporter" in Henry County, Georgia, and was the founding editor of The Washboard Weekly, an "edgy tabloid" in Johnson City, Tennessee. It went out of business due to a lack of advertising. In 2022, Clark was featured as the voice actor of Wiggly Worm 2 in one episode of Bee and PuppyCat, a streaming television series.
Before joining HowStuffWorks in 2007 he was a self-described factotum who held many jobs. He had a paper route, washed dogs, and held "jobs that involved shovels." Before recording his first episode in 2008, Clark had never listened to a podcast, and didn't know what one was.
Charles W. "Chuck" Bryant
Charles Wayne Bryant is always introduced on the show as Charles W. "Chuck" Bryant, but fans often refer to him as "Chuckers." Born March 15, 1971, Bryant was raised Baptist and played church league sports, although his "constant struggle with religious upbringing" has been "well documented over the years."Bryant grew up in Stone Mountain, Georgia but his family lived in "rural Mississippi since the dawn of time," as well as Tennessee. Chuck is also part Choctaw Indian. He attended Redan Elementary School where his father was the principal and graduated from Redan High School. His mother, Dianne, was also a teacher. He has a brother named Scott who is three years older. His sister Michelle, who is six years older, is married to Karsten S. Heckl, a Marine Corps General. His uncle, Ed Bryant, is a former Republican member of the U.S. House of Representatives from Tennessee. Bryant once appeared on the cover of Guideposts magazine as a child.
Bryant earned a bachelor's degree from the University of Georgia where he studied English. After college, he took classes in screenwriting at New York University's film school and then moved to Los Angeles for four years. He has also lived in New Jersey.
Bryant is married to Emilie Sennebogen, and in 2015 the couple adopted a daughter, Ruby Rose, who shares a birthday with Clark. As a self-described "crazy animal person," he has multiple pets. He plays the guitar in an "old man band," called "El Cheapo." Humorist John Hodgman is a "dear friend."
He is the author of six screenplays, including one about a Southern Baptist church called "Sweet, Sweet Spirit," but did not find success in that field. While in Los Angeles, he was a production assistant on TV commercials, a few indie movies, and music videos, which he says helped with the TV version of Stuff You Should Know. He was hired at HowStuffWorks after a friend got a job there and submitted the first act of a screenplay as a writing sample.
Podcast
History
The podcast was launched on April 17, 2008, with Clark as the solo host. Bryant made his debut a month later on May 13, 2008. Bryant became the permanent cohost on July 15, 2008. The podcast, which was named by Clark, began as an attempt to re-purpose some of the written content on HowStuffWorks.com. Clark had never listened to a podcast before he recorded his first episode in 2008. Jesse Thorn has held the name up as a model of how a podcast should be named saying "it's like daring the listener not to listen to it."The podcast has steadily grown in popularity since its introduction and has made appearances at events including South by Southwest and Comic-Con. On October 26, 2017, Stuff You Should Know released their 1000th episode. Several episodes have been recorded during live events, including two during their World Tour of Canada in September and October 2014. While in Canada they also participated in the Northwest Podcast Festival, at SXSW in 2011 and 2012, and New York Comic Con in 2012 where they recorded their discussion entitled "Time Travel: Science Fact or Science Fiction?"
During the 4th of July weekend in 2011, there was a Stuff You Should Know About America marathon on Sirius XM radio. It featured previous episodes, as well as a live segment with Wyatt Cenac and Hallie Haglund of The Daily Show as well as Joe Randazzo, Joe Garden and Jill Morris of The Onion. Their 420th episode was on medical marijuana, although this was reportedly a coincidence.
In 2011, the podcast added "Bonus Videos" to the podcast feed. These consist of humorous 60 second videos where Clark and Bryant converse about subjects they covered on previous podcasts while doing a variety of random activities. As they speak, the scene changes repeatedly to something completely different, though their conversation continues uninterrupted as though nothing had happened. These clips have also aired during commercial slots on Science and appear on their YouTube channel.
There is one unaired episode on animal detectives that they hope will never be published. They have repeated a topic three times. They revisited the topic of Murphy's Law in 2011 after first doing it in 2008. As one of their first episodes, it was under 6 minutes in length. They also accidentally repeated a podcast on customs. The first time was in 2010 and the second was in 2016. In July 2018, they released an episode on recycling as an update on their first one, recorded over a decade ago.
On November 7, 2018, Josh Clark created a podcast called The End Of The World with Josh Clark, a 10-episode series that discusses what dangers lie in humanity's future., their office and studio was in the Ponce City Market in Atlanta. and their studio is slightly larger than a broom closet and features "kooky" items listeners have sent in, including wedding invitations and photoshopped movie posters with Clark and Bryant's faces on them. The office has a large mural depicting the formation of an idea, a research library, and giant question mark-shaped conference table.
Format
The podcast, which was the second on HowStuffWorks, has been described as the "heart and soul of the operation," with the "well researched" episodes cover a variety of topics from the fields of "science, history, urban legends, and pop culture, with the occasional conspiracy theory thrown in for good measure." Clark and Bryant have a conversation about the given topic such that, by the end, listeners have a "basic working knowledge of that subject." Clark has said they are on a "never ending quest to explain absolutely everything there is on planet earth and beyond."Their "biggest hits" include episodes on Spam, hangovers, tipping in restaurants, cheese, Barbie, and pinball. The topics that get the greatest response from listeners include death and grieving, and episodes that received "less enthusiastic feedback" include shows on homelessness/addiction, Tourette's Syndrome, and transgender issues. Episodes are normally around 45 minutes in length, although for more in-depth topics the show occasionally runs long as an hour or more. Initial episodes were much shorter in duration, often less than 10 minutes.
One of the reasons the hosts believe the show has been so successful is that they are "definitely not experts" in the myriad subjects they explore, but are instead "just guys who enjoy research and very curious." Their formula "is part self-deprecating humour, part infectious wonder and part self-discipline to go their separate ways and do all their own research and reflection before they get to the studio." They often try to surprise one another with their research, and do not have a script or a time limit before they sit down to record. Likewise, they do not rehearse beforehand.
Most episodes end with listener mail, although there is an occasional segment known as "Administrative Details." Listener mail debuted on November 25, 2008, in the episode named "How Albert Einstein's Brain Worked". On that episode, they called it "Correction Time." The first time it was known as "Listener Mail" was on January 8, 2009, an episode that was inspired by a listener's email. During the Listener Mail portion of the podcast on April 11, 2013, a new jingle for the show was introduced. It was written and recorded by Rusty Matyas of Winnipeg, Manitoba in Canada, a musician and fan. , another fan who covered Matyas' band, The Sheepdogs, has produced several new jingles for the show.
The show's regular producer is Jeri "Jerome" Rowland, who is assisted by a variety of regular guest producers, including Matt and Noel. Other staff includes Rebecca, the web producer, as well as Sherry and Joe. In 2017, there was a staff of 35.
