Factual error: In "Our Son, The Man", Greg wants his own room. One night, while in bed, Mike and Carol discuss their options. Carol says "How about the attic?" Mike responds with "That would be fine if Greg were only three feet tall." Later they give Greg the den for a while. However, in "A Room At The Top", after cleaning out the attic, which was now full size, both Greg and Marcia want it for their own private room.
