The Ghost of A. Chantz - S4-E3
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.
Suggested correction: Or they sleep in twin beds because he steals the pillow and takes the covers when they tried sharing a double bed.
It's not true that Rob steals pillows... Because every episode Rob has only 2 pillows. Unless he steals them in the middle of the commercials... and then they vanish before the next scene.
The Ghost of A. Chantz - S4-E3
Continuity mistake: When Rob and Buddy are talking after arriving at the cabin and discussing the lack of wood that should be there for 3 years, a white birch like log on the very top of the pile inside the fireplace. The camera cuts to Buddy saying something about the ghost burning it, and when the camera cuts back to Rob the white birch like log is missing from the fireplace. Then when we see Rob making the pull out bed the log reappears back on top of the wood pile in the fireplace.
A Vigilante Ripped My Sports Coat - S4-E5
Continuity mistake: Right before Rob starts the story to Sally and Buddy about how Jerry ripped Rob's sports coat, the box is on the floor. When we cut back to Rob, Buddy and Sally later on. The box isn't even in the room anymore. Then later on when Mel comes to pick up the box, it's back on the floor again.
Romances, Roses, and Rye Bread - S4-E7
Continuity mistake: When Sally lets Burt into her apartment, her hand is on her forehead and then all of a sudden it's down by her side.
Factual error: When Rob climbs up the elevator shaft, he comments on how greasy it is, and when he jumps back into the elevator, he wipes his hands on his shirt but not a bit of grease shows on his clean white shirt.
Character mistake: Rob tells the people that are about to get on the elevator "my wife is expecting a baby!" In all the other episodes where "she's expecting a baby" as well... No change in stomach size at all! Not a single sign of pregnancy... (After 12-16 weeks it starts to show that the baby is there.) Even before Richie was born, still flat as a pancake.
Other mistake: After Lyle gives back Rob and Laura's watch's and the $51, Rob doesn't get his ring back.
Three Letters from One Wife - S4-E10
Factual error: Millie mails 14 letters to Alan Brady with names of dead relatives, and to give them different postmarks she says that she drove all over Westchester and southern Connecticut to mail them. The next day, all 14 have arrived. Mail crossing a state line would not likely have made it overnight.
The Death of the Party - S4-E13
Continuity mistake: When Laura puts the ice cream in the freezer, the freezer is full, however when Millie brings over the ice they are able to put it in the nearly empty freezer.
The Case of the Pillow - S4-E21
Continuity mistake: In some of the courtroom scenes you can see feathers flying around, before Rob spills feathers all over the courtroom.
Other mistake: Rob's watch is completely blank. No numbers, no hands or the knob to adjust time. His watch is fake. (It may be that way in all the episodes but this is the first time I noticed it so far).
Continuity mistake: When we first see Richie at the beginning of the episode he has extremely dark "bruises" all over his hands, arms and face. But by the end of this episode all the bruises are gone except for 1 which is on his face below his left eye (on our right). Bruises do not just vanish in 2 or 3 days if they are that bad.
Continuity mistake: The guy yelling about asking to see people that work in the office building in this episode gets told several times "no they aren't in". He sprints away from the desk with briefcase in hand, he's past Rob on the other side of the room. When they cut back to the lady you still see the guy's music transcripts and his brief case on the lady's desk still in his hand. (00:21:17)
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.
Suggested correction: The part is Rob checking to see if he had the right number.
Other mistake: Buzzy said that Rob made a song making fun of Sergeant Foley. However, Rob's Sergeant was Lebost.
Other mistake: Rob mentions Buzzy Potter to Sally and Buddy as if they knew him. Rob and Laura did the Army stuff way before working on the Alan Brady show. Also, there was no mention of Buzzy Potter anywhere else in the series. There for Sally and Buddy wouldn't have known Buzzy, but Millie would have known him.
Your Home Sweet Home is My Home Sweet Home - S4-E25
Continuity mistake: The Petrie house (where Rob and Laura, Jerry and Millie are standing together bickering) is completely different from the episode "Where Did I Come From?" and a few others.
Your Home Sweet Home is My Home Sweet Home - S4-E25
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.
Suggested correction: No, the Petries buy the house with the rock, but swap it with their best friends and buy the house next door. Therefore Jerry and Millie have the rock in the basement.
Rob has to pay half the cost for Jerry to seal his basement every year. The reason why is because Rob's rock redirects water that ends up flooding Jerry's basement.
The Petries did buy the house with the rock. At the end of the episode Rob explains how their rock caused flooding in the Helper's basement.
Your Home Sweet Home is My Home Sweet Home - S4-E25
Factual error: When Rob is on the phone with the Realtor guy they talk about what the Petrie's soon to be house will look like, what's in it, what won't be in it. Yet neither of the houses (Petries and Helpers) are the same in any of the episodes and none of the stuff that is mentioned in this episode are in any episode no sling chairs, no pine wood or panelling etc. The 2 houses are completely different.
Never Bathe on Saturday - S4-E27
Other mistake: When Laura is stuck in the bathtub, she tells Rob "there's a full length mirror on the back of the door" Rob runs full speed right into the door with his shoulder. Yet with his weight, height, BMI he would have immediately knocked the mirror off the door the 1st hit, not after the 3rd time when Rob put his elbow on the door. Also the mirror wouldn't have taken 9 seconds to finally fall with the height of the door. (00:17:34 - 00:18:26)
