Casting Sam Elliot as Ron Dunn, the Doppelganger of Ron Swanson was a stroke of genius. I never would have thought of him even guest-staring on the show, let alone as someone that mirrored Ron in every way, shape or form. Almost. Of course the initial meeting would be positive as Ron Swanson would find a kindred spirit. But that was short-lived when he was too much of a hippie. Too bad this was a one and one cameo. It would have been awesome to get a multi-episode arc. I also thought Donna's new assistant was hella funny.
