Classic TV buffs will recognize guest star James Karen in this episode as the patient-weary boyfriend of Dorothy. He is known for portraying nastiness as well. Two of his most infamous characters in TV have been the greedy proprietor who causes the people of Walnut Grove on "Little House on the Prairie" to blow up their town to prevent him from taking ownership of their property. The other is as a despicable racist who tries to force all black people out of the apartment building where "The Jeffersons" live.
The first episode where, at about 18 minutes, a sidewalk from the driveway is evident. It still makes no sense in relation to the home's interior, but at least it shows a way into the house.
