I've been on a binge with this one. Kyle Kinane is one of my favorite comedians, he and Dave Stone (another great comic) discuss different conspiracies/cryptids. They are not professionals by any means on any of the topics (and usually just end up talking about fried chicken) but it's always interesting and really funny. It sounds like hanging out with two buddies talking about weird shit you read on the internet.
Seconded.
Bizarre States; discovered them, as they had Kyle Kinane & Dave Stone on as guests. Similar subject matter, a lot more structured. They also pepper in recent weird world news events and listener stories.
Lore is another podcast rooted in the supernatural, focusing largely on urban legends and the historical origins thereof. Be forewarned, many people can't get over the narrator/creators voice. If you dig it, the guy also has several books/audio books out there & a tv adaptation of his podcast on Amazon video.
The Todd Barry Podcast offers a similar conversational feel as the BMP but w/o the promise of the supernatural.
The Hound Tall with Moshe Kasher is a live show featuring one expert on a subject and a panel of comedians to punch it up.
Here We Are w/ Shane Mauss deals largely w/ brain science and psychedelics
To the guy who likes the Joe Rogan podcast but hates Joe Rogan, I'd say You Made it Weird is more what you're looking for than WTF, though both are good.
