He laughs a LOT. And he has slightly hippy ideas about how people work. It can get very deep. I usually find it a bit much, and I end up getting annoyed at him, so I don’t listen unless the guest is up my alley. He had Dan Harmon and Tim Minchin in close succession, those were good.
Let me third Dan Carlin’s Hardcore History my favorite is World War I Blueprint for Armageddon.
I just started Kevin Stroud’s History of English Podcast, very interesting. He starts with proto-European and 98 episodes later is only at the Magna Carta.

The Last Podcast on the Left is the best.
Just realized that I didn’t add a “second!” for Last Podcast on the Left. Their research is thorough and painstaking. They have also, over the course of a five-part series, come up with what I think is the best theory as to who Jack the Ripper really was:
No one. At least, not any one person. Their conclusion was that two of the murders were committed by one individual, two by another, and one by a third person. The murders were completely unrelated. The newspapers portrayed it as a single madman because that sold more papers.

I enjoy History of English very much. Although given that it’s a podcast about language, Stroud’s slight southern accent occasionally makes his illustrative pronunciations interesting. 
I also listen to Jamie Jeffers’ The British History Podcast, which is a narrative history of Britain, starting at the Ice Age and moving forward. It moves fairly slowly–he’s 250 episodes in, and the Normans haven’t even shown up yet–but that’s because, unlike a lot of histories of England, he doesn’t skip over the Anglo-Saxon era in his eagerness to get to the Vikings and the Normans. So rather than limiting his coverage of the early Middle Ages to Alfred the Great, as so many people do, you’ll learn about kings like Ida, Offa, Oswiu, Penda, and AEthelbald. People you’ve probably never heard of, but whose reigns were as interesting and eventful as any of the more familiar English kings of later years. Jeffers also has a breezy, irreverent style–he plays the Wilhelm Scream whenever one of King Ida’s many sons gets killed, for instance–which makes it fun to listen to.
Oh No With Ross and Carrie is very good. We listened to the series where they joined the Church of Scientology while driving back from seeing the eclipse.
The Skeptics Guide to the Universe is a great podcast.
I can’t stand Startalk. It should be called, “Shut up, guest, and let the star talk” because Neil deGrasse Tyson continually interrupts everyone with his banal observationa and lame jokes.
Econtalk with Russ Roberts is the best economics podcast there is, IMO.
Waking up with Sam Harris is my current favorite political podcast, mainly because A) it’s very smart, and B) Harris seems to making an equal amount of enemies on the right and left these days, so it’s a perspective you don’t get if you stay comfortably in the echo chamber of your own ideological programs.
Criminal is very good. After being impressed by Serial, I subscribed to a bunch of true-crime related podcasts, but this is the only one I still listen to. Too bad it’s only monthly.
HowStuffWorks does a bunch of good podcasts. My favorite is Stuff to Blow Your Mind, perhaps followed by Stuff They Don’t Want You To Know, Foodstuff and Stuff You Missed in History Class. Oddly, their flagship How Stuff Works podcast is the weakest, especially for science topics (the two hosts have very poor understanding of science).
Sawbones and Oh No Ross and Carrie are fun in a relaxed way, perfect for when I’m not in the mood for something more emotionally taxing (like This American Life).
The Skeptics’ Guide to the Universe is my favorite science/skeptic podcast. Skeptoid is good too, but short.
If you like This American Life and The Moth, try Snap Judgment.
I really dislike How Stuff Works because the two hosts are two guys who really think they’re funny when they aren’t at all. Same with “True Crime Garage”, they will stop a serious/interesting conversation to do some improv and it’s the dumbest most obvious jokes you can imagine.
That might be part of it, but I really think the biggest problem is that they seem to present topics they don’t understand, and aren’t interested enough to research properly.
The other hosts on the HowStuffWorks network are much better - the hosts genuinely seem to be interested in what they are talking about.
Because of the recommendations here, I decided to check out an episode of The Last Podcast On the Left.
Is it always like that?
Is what always like that?
I think the last podcast on the left has potential, but the constant banter reminds me of morning zoo radio and I find it a turn off.
Would it be bad form to recommend one NOT to listen to? 
S-Town. yuck.
Hollywood Babble-On with Kevin Smith and Ralph Garman, usually done as a live show from the Improv.
Has anyone listened to Norm Macdonald Live? I enjoy it.
I mentioned it before, but I’m into True Crime podcasts but the podcast True Crime Garage which I’ve seen be recommended on other websites is incredibly bad.
The two hosts are very dry but at the same time try to be funny and as a result the jokes never land. There’s so much filler in the podcast it’s astounding, they start each episode with a boring “What are we drinking” craft beer segment, then they’ll just play for minutes at a time 911 Calls or News Reports of the crime with absolutely no context or editing so they seem to take forever, then they’ll often repeat the same details of the case over and over again “just to remind listeners” despite the fact it’s an hour long podcast, nobody listening needs to rehear something that happened 20 minutes ago. The host and cohost love to talk in circles with one asking a question than the other answers, then for some reason asks the same question but slightly differently worded. It was so frustrating I gave up 3 episodes in which is 3 hours I’m never getting back.
Is The Last Podcast On the Left always like the episode that I heard? I didn’t know quite how to describe it.
Yeah, something like that. It seems like there might be some interesting subjects that they talk about, but amid all the stupid jokes and bad voices it’s too much trouble to extract any good parts. It’s like eavesdropping on a frat house.
The Reverend Peyton’s Big Damn Band. It’s generally recorded on the road, and they have a seemingly endless series of stories. They play 200+ concerts a year, and one of the things they set out to do was actually see the world as they travel it, not falling into that trap so many musicians do of seeing the world only as airports and concert venues. They are passionate fishermen and sportsmen, fishing everywhere in the world.
If you only listen to one episode,the one where Rev tells about his run-in with Ted Nugent is an absolute classic.
