PARKS! Pt. 1: Social media gone 'wild'
"To avoid crowds, visit areas that are less crowded." These comically obvious, wise words come from the Twitter account — ahem, X account — of the National Park Service, who has been hitting it out of the park lately (get it?) with its social media content and reaping viral rewards. Who is behind this material? And why has a more than hundred year old government agency chosen to let its hair down on social media?
Amory and Ben talk to the National Park Service's lone social media ranger, Matt Turner, and to Sarah Southerland from the Oklahoma Department of Wildlife Conservation, whose delightfully outrageous social media presence has captured the hearts and funny bones of hundreds of thousands of people.

Best of Summer: MEMES: Scumbag Steve
If there is an OG meme in which a human is the star, Scumbag Steve is it. He spread across the internet like wildfire in 2011 as a universal representation of dudes who are the worst. And, like any person grappling with immediate internet fame, Blake Boston — the man behind Scumbag Steve — tried to capitalize: merch, rap songs, public appearances.
But the full story of what happened to Blake — and his family — has never been told. The Scumbag Steve meme became a bargaining chip in a custody battle, a complicating factor in meeting his birth mother, the cause of fights with extended family members, a source of anxiety attacks, and an echo of trauma. In this episode, we go past the origin story of Scumbag Steve and learn about Blake’s real struggles with PTSD and abuse — and how trauma has brought him and his mother, Susan Boston, even closer.
