Wow... I stumbled on this in my Stitcher feed and expected it to be a short series on the myth itself. We've all likely heard of the black cabinet that hurt children and was checked by Men in Black. It has become part of pop culture from the Simpsons mall arcade to a NIN/Jeff Minter music video (I mentioned in a RB thread here).
Instead this team dives in from a journalistic point of view. I had no idea there was a man in Portland who claimed to be part of the Polybius experiment back in 1981. They even find a reporter who wrote on this arcade in question back in the time-frame. After looping her in ~35 years later is where it starts getting weird.
No spoilers here in OP, but keep listening... by the conclusion of episode 2, you'll think Bobby is perhaps a little nutty. By the end of episode 3 there are some very strange coincidences coming from three or four different parties and deep dive sources. These share some odd similarities to his story and the overall lore
