Stupidity: Laura is shrieking, shouting and yelling. Rob is breathing things during the "night." But Richie never wakes up ever during the time it's dark "outside." However in other episodes Richie comes running in complaining about how loud everyone is. Real life if someone is shrieking or screaming us humans would be scrambling to find out what all is going on.

Starring: Dick Van Dyke, Mary Tyler Moore, Morey Amsterdam, Larry Mathews, Rose Marie
It May Look Like a Walnut! - S2-E20
Character mistake: Rob is having a nightmare, part of which involves the disappearance of his thumbs. When he finds Laura at home, the script calls for him to say, "I want you to help me get my thumbs back," but he actually says, "I want you to help me get my thumb backs." His thumbs are also still there but hidden (you can see a portion of them in one frame of the episode).
Rob Petrie: I want to take a nap before I go to sleep.
Harrison B. Harding of Camp Crowder, Mo. - S1-E6
Trivia: Rob tells the police over the phone "Get a prowl car to 148 Bonny Medow Road." 148 was also Dick Van Dyke's weight during the TV series.
