Ok all jokes aside I was pretty stoked to hear Brad mention this podcast. I wouldn't call myself a history buff, I found it interesting in school but I don't read history books or anything but if you are even the least bit interested in history you really should check the podcast out.
The dudes name is Dan Carlin, he's an amateur historian (or as he calls himself a fan of history) and it's basically just him talking about different events, but the way he talks and describes events is incredibly engaging. Seriously there's not many people I can just listen to talk for hours but he's one of them. I just finished learning about the fall of the Roman republic and it's a 6 episode series, the last one being 5 hours long. There's a series of episodes on Genghis Kahn that is totally fascinating. If you have the slightest interest in history you should check it out.
