Other mistake: Any time Rob has to go to a doctor or to Jerry to get his teeth worked on, if you look at the window behind him and whoever is working on him. It's the same buildings every time. Even though he goes to different doctors. Also, that window and the curtains are also the same exact windows and curtains in Robs office.Liz Blue 1970
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).
Other mistake: When Rob dials the radio station, he dials the phone number and then looks it up in the phone book. He covers for himself, and then has a hard time keeping a straight face afterwards.Pam-I-am
Factual error: When Rob tells the name of the street he lives on in this episode "Bonnie Meadow Lane" that was not the same as the past episodes which was "Bonnie Meadow Road" in all the other episodes except for when Rob and Laura were buying the new house beside Jerry and Millie's house.
Other mistake: Evan from the insurance company comes over to ask Laura and Rob several questions but not once does he find out any names from the party. But the next day Buddy, Sally, Mel, Jerry and Millie all get really angry because of Rob and his interrogator just assuming that they stole the watch.
Continuity mistake: While Rob is by himself at the WOFF radio station the "On the Air" sign is above the door behind him and there is a giant window there beside the door. When Rob is doing the 100 hours of being on the radio the door, the window and room are completely different. No door, record disc holder, other equipment, or window behind him.
Continuity mistake: The bathroom door that Rob shot the knob off with the gun is not there in 1 scene, but suddenly reappears a little bit later back on the door, he's able to open and close the door with ease when he is in the bathroom with Laura while she's getting out of the tub. (00:20:30 - 00:22:00)
Revealing mistake: When Rob is "playing" the piano none of the keys on the piano look to actually be pushed down. Also when he's scratching his back with each of his hands the notes on that same side of the piano are still played. He's not actually playing the piano. (Except for the last 2 notes or chords). (00:02:46 - 00:03:27)
Plot hole: In the episode "That's my Boy" when they bring Richie home from the hospital, Rob and Laura are living in the new house they have. However, in the episode "Where did I come from" when Laura went in to labor, they lived in a different house. They couldn't have moved while Laura was in the hospital.Pam-I-am
Continuity mistake: In this episode it is shown that the Petries live in a house with a huge rock in the basement. In the episode where Buddy's brother, Blacky visits "Hustling the Hustler", they play pool in the basement and there is no rock.Pam-I-am
Factual error: When Laura and Sally are about to go to the bedroom, Buddy and Rob are going to sleep in the living room of the haunted cabin. Rob and Laura tell Buddy and Sally things like how he steals the pillow and he takes all the covers at home. However at home, they sleep in twin beds so they shouldn't know such things. However, they do have a son. They had to share a bed at least once in their marriage.Pam-I-am
