Other mistake: Laura and Rob do not like having guns in the house and Laura is terrified about having them in the house... Yet in this episode... There are 2 guns in the basement displayed right next to a giant deer head on the Cross beam in the middle of the room up high. Neither of them care that the guns are there.
Other mistake: Laura tells Sally, Rob and the rest of the staff she's going to have a baby in a few days or so while she was at the Alan Brady Show. If Laura is going to have a baby she should have the baby bump the whole episode while she and Rob are reminiscing. (00:05:00)
Other mistake: Rob and Laura's old house changes from episode to episode when they go back in time reminiscing. 1: Petries and Helpers are in Rob's old house the size of that house was a trailer sized house. 2: Rob was in the Army the house was the size of a small apartment.
