This is one of those Simpsons episodes that feels like it went by really fast. It's almost a shame that a lot of the focus was on Marge, because I think they could have gotten more mileage out of C. Carl Carlson's rise to power and loyal lackey Homer Simpson. Likewise, the resolution of the near-affair between Marge and Ned seemed to come and go so quickly.
