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: If Rob is that easily hypnotized then when Rob's friend hypnotized Millie he would have gone out light a light same when he did Laura and Jerry. Rob would have been out right then and there for all 3 of them... Not just when he did Buddy.

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)
Suggested correction: She says no such thing in that scene.

Other mistake: The desk that was Rob's Grandpa's in this episode was not the same exact desk that Rob inherits in "The Great Petrie Fortune" after his Grandpa passed away. (00:17:40)

Other mistake: Richie has Rob's electric razor from Richie's bathroom. Rob and Laura have a bathroom for themselves... Rob doesn't need to put his stuff in Richie's bathroom.
