I didn't read this entire thread, so if they are duplicates, sorry.
Here's my list of weekly podcasts that I must listen to.
Bertcast's podcast- This is Comedian Bert Kreischer's podcast. I'm a big fan of Bert, and his podcast tends to be silly a lot. It makes my day go quicker.
Bill Burr's Monday Morning Podcast- Similar to Bert, Bill is a comedian. His podcast is typically just him alone ranting about things. He also played the red headed guy on Breaking Bad.
Mohr Stories- Another comedian, Jay Mohr. He never does a solo podcast, but a lot of them are very interesting anyway. He's married to Nikki Cox, and she randomly appears on different episodes. I really liked the first 20 or so the most. The rest are entertaining, but I laughed really hard at the first few.
SModcast- This is Kevin Smith's (the director of Clerks) founding podcast. He now has an entire network of them, but I stick to this one. He pretty much just does pot talk in these. Ever since he finished Zach & Miri make a Porno, that is. Seth Rogan got him smoking again, and he does it a LOT now. Really odd ball shit, and a lot of it is silly.
Girl on Guy with Aisha Tyler- Aisha is the voice of Lana on Archer. She's another comedian, but she's a video game nerd also. She does very in depth interviews with various people. She actually did one with one of the faces of IGN a week ago. It was interesting.
The Doug Stanhope Podcast- He does these VERY few and far between. Like months apart, typically. Doug is an unusual guy, so I go out of my way to listen to them.
Ok, those are the podcasts that I listen to every time I can. I used to have The Bryan Callen Show and Joe Rogan Experience, but I've since cut them out. Joe does entirely too many LONG podcasts, and a lot of Bryan's were becoming very dull. It's typically the guests he would have. Writers of some book of poems or some other thing that I personally really don't care about. I did, however, enjoy all of the ones with his Father. He was a president of like Capital One or Chase. Really really knowledgeable about the banking world, which was interesting to listen to.
