Factual error: Rob mentions several times "I broke my cheek" if he actually broke his cheek we could see a spot there, either a divot in his face where the accident happened and was not fixed, or we would see a indent line from where they put stitches on his face. We see neither of these.
Factual error: Alan Brady and Mell's offices are a few floors up. Yet Rob, Buddy and Sally's office window shows that they are way higher up than Alan and Mell's office - you do not see the roof tops of buildings anywhere from Alans and Mell's offices.
Harrison B. Harding of Camp Crowder, Mo. - S1-E6
Factual error: This is the only episode that Harrison is seen, mentioned or even talked about. But in all the rest of this series there is no Harrison. Both Harrison and Rob mention that he was the guy on the spot light fir the shows... But not one time did we see a spotlight on Rob in any of the episodes.
Factual error: Talking to the lawyers, parties, or witnesses about anything. This will give the impression that something unfair is going on. And is also illegal. Which Rob was doing during this whole episode.
Factual error: Rob says to his doctor that they have catfish at his home yet you never see the catfish ever. The only time you see fish in this series is on a plate or in the episode "The Night the Roof Fell In" which weren't catfish. (00:11:33)
A Man's Teeth Are Not His Own - S2-E13
Factual error: Rob is in the middle of eating a sandwich. You can't break a tooth on a sandwich unless it's frozen, cement, glass or made of ice.
Suggested correction: Rob specifically said he broke the tooth on a chicken bone that was in the sandwich.
Factual error: While Rob is roaming the house with a gun in his hand he chops the metal tube that the wood burning stove in the living-room is connected to. However since in real life the metal tube would be thick and insulated the tube he dented with his hand at that speed wouldn't have been damaged at all. Also, it could have broken his hand or at least sprained his hand where he wouldn't be able to use it or feel like using it.
A Surprise Surprise Is a Surprise - S2-E30
Factual error: Buddy asked Sally "why haven't you had a birthday...?" Yet a few episodes ago (Season 1 Episode "Where you been, Fassbinder?") Sally had a birthday she cried and cried. Buddy and Pickles, Rob and Laura were all there.
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.
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.
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.
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.
Factual error: In the Army or Military it is mandatory that the name tag is worn the same as the Dress Tan/Green/Blue and must be worn in either configuration. Ribbons are worn the same as the Dress Tan/Green/Blue. Special Skill Badges, Distinctive Unit Insignia (Unit Crest) are also worn the same. Rob and everyone else in the army was not wearing a name tag in any of the episodes.
The Great Petrie Fortune - S5-E6
Factual error: Rob tells this lady that the guy that passed away was his great-uncle and that the last time he saw him was when Rob was 12 years old... This is the same Grandpa that was also seen in the episode "What's in a Middle Name" (in this episode in season 5 Richie would be 10 or 11. But the other episode he was supposedly 8).
Suggested correction: You seem to be confused about Hezekiah's relationship to Rob. He is Rob's great-uncle which means he's the brother of Rob's grandfather, the character from "What's in a Middle Name?" (And by the way, the scene in that episode took place before Richie was even born. The fact that they were arguing over his name should have been a clue).
Factual error: Rob told Sally and Buddy that he hit "Boom Boom" in the appendix. When we see Rob punch that guy he hit him right in the upper stomach. Rob would have won the boxing match. Because "below the belt" refers to all the area of the body that lies below the line of the opponent's navel, including the groin area, legs, and crotch.
I Do Not Choose to Run - S5-E16
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.
Factual error: Rob and Laura went on only 1 honeymoon back in episode "Honeymoons Are for the Lucky" (while Rob and Laura are in Missouri, at a hotel less than 1 hour away from Camp Crowder) yet in this Alimony episode Rob and Laura say they were in Texas but went to Mexico for their only honeymoon.
The Man from My Uncle - S5-E27
Factual error: The Government Agent says "we want to use your house for base operation for looking at the house across the street. Rob says "Jerry helper!" yet Jerry lives on the same side of the street (closest to the den, across from Rob's bedroom). Someone has their houses mixed up.
