I'm not going to say they got beef but I remember the Bill Burr episode when Burr and Redban got to arguing at the end over copyrighted material. Burr then went on his show and shytted on Redban calling him Rogan's assistant. Rogan on the next episode basically stood up for Redban and kind of made it seem like Burr was exaggerating some things on his show and they didn't really know or as cool with each other as Burr was making it seem when he was on JRE. That being said I don't know if they squashed it or not or if either has been on each others show since i haven't listened to either consistently in a few years but if they don't get along I could see that being the reason why cause neither one of those dudes seem like the type to just apologize.
Well recently burr said he needs to go on Rogans show again or have him on his but he's lazy .Rogan seems enlightened enough to squash it but honestly red ban is useless without a comedian guest and he's not funny . On the recent ari shaffir one
