Factual errors: The series is set in Chicago, and in the one episode, Jim buys the cemetery plot next to Bronko Nagurski's grave. Bronko Nagurski is buried in International Falls, Minnesota.
Continuity: The front porch swing at the house. When there is a picture of the front of the house, the swing is parallel with the front of the house. When there is a scene on the front porch/front door area, the porch swing is perpendicular to the house.
