Lately I have listened to a bunch of episodes of the Flop House. It's more or less another entry in the "three guys riffing" category, but I like how nerdy it is. The hosts are kind of eggheads, who have actually read some books, and that makes for a refreshing contrast from the L.A. podcast crew. They go really deep with obscure movie and Marvel comics references, which is OK by me.
I have also listened to a lot of Bill Burr's podcast. I like him a lot, and the podcast is often very funny. But man, is it unproduced. And too much sports talk! The reads that he does for his promo spots are so bad, I almost can't believe that his sponsors put up with it. Same with Doug Benson: it sounds like he records his in a rental car (and he probably does).
