Dan has been there the longest, he was an original fan that is literally just like Jamie for Joe Rogan. He's always been a producer/research guy to bring up links from way way back.
The next useful personnel is the sound board retard. A.B. was only hired because he made a video countering a known H3 critic on youtube, Gokunaru, but his Muslim background probably helped. Everyone else is a waste of money, the personal assistant wife, Olivia is like the mandatory female cohost radio stations across the country force men to take on for demographics and advertisers. Cam was a photoshop memer, the Swedish retard is truly a question mark. Pocket IKEA brand pewdiepie?
Any episode I liked predated the crew add-ons. The Bert Kreischer interview was pretty good. The fundraiser superstream with Alex Hirsch(Gravity Falls creator) and Justin Roiland(Rick & Morty creator) had some good moments too.
