Just started listening to this religiously when I drive, especially if I'm in heavy traffic. These podcast opened my mind to a lot of shyt I think its great, the Neil degrasse Tyson and Kevin Smith ones are next up on my rotation
I've listened to each one for the past 2 years or so. They are either entertaining or informative. It's akin to a philosophy discussion in a lot of cases. Some science but ultimately Joe, IMHO, knows he don't know shyt and is just out there speaking his mind and questions, which often lead me to my own questions. It's a solid podcast and always entertaining. The "type" of guest is so damn varied too. Scientists, authors, comedians, doctors, MMA fighters, nutritionists, trainers, cooks, hunters, tv personalities, youtube product unboxers, it's like a jack of all trades podcast that touches on so many issues.
