He's an observer, he talks about him and his life, on a similar level as peter kay and billy connelly. I'd say he was even funnier than peter kay as it appears to be less rehearsed, Kay tells the same jokes/scenarious/situations where as Russell's intelligence, speed and delivery brings him through without relying on rehearsed stuff - as exampled in his radio/podcasts and various TV appearances, compared to Peter Kay on Parkinson where he brought on party hats and cake - wow.
