Character mistake: Rob is telling Laura about how Buddy and Sally work he says "Sally is the only one who can type with all her fingers." Yet Rob can type with all his fingers and doesn't say anything about that.
Will You Two Be My Wife? - S2-E17
Revealing mistake: While Rob is asking for 2 passes for 3 days in the Captain's office the plant that is outside the "closed window" behind the open blinds has leaves can be seen in between each of the blinds. Which means that the tree isn't actually outside and there is no window, just a window frame. (00:04:40)
It May Look Like a Walnut! - S2-E20
Continuity mistake: The episode opens with Rob watching a horror movie on television. The bedside clock shows the time as 9:05. At the end of the episode 23 minutes later, the clock shows 9:10.
Continuity mistake: The number of glass "pea pod" shaped sphere balls change through out the series. In "Don't Trip Over That Mountain" there were only 3 spheres. In several episodes there were 4 spheres and in others there were 5 of them.
The Great Petrie Fortune - S5-E6
Plot hole: If Rob was just 12 or 13 when he last saw his grandfather (that's what they said in this episode, also he never called his grandfather ever from what it looks like) then his grandfather wouldn't know that he has been working on a TV program. (He started working on the Alan Brady show when he was 20, not before).
Suggested correction: First of all, it is Rob's great-uncle, not his grandfather. And what makes you think he wouldn't know? Off the top of my head, I can think of a dozen ways he could have known. He was watching the show and saw Rob's name in the credits. His brother called him to brag about his grandson. He read a magazine article about television comedy writers. Etc. Etc.
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.
Buddy Sorrell, Man and Boy - S5-E22
Other mistake: Rob got a new watch for his birthday a few seasons back. Yet he's still wearing his old watch. And also his watch time says it's 3:00. Rob and Sally would still be at work if it was actually 3:00.
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).
Character mistake: Rob is reading the news or his lines and instead of saying "the stay awake record of 100 hours" he says "stay away record of 100 hours."
Suggested correction: Of course he does. He is punch drunk from the lack of sleep. That's the point.
On hour 24 Rob couldn't even say the rhyme at all, he also sounded slightly drunk, also his lower eye lids got dark. I have been up for 48 hours before and my eye lids never turned that color also I didn't act slightly drunk like that either. So it's not actually true to life here.
1) You can't assume your personal experiences is typical of everyone's. 2) I doubt your experience was very funny. In a comedy, stupidity overrides "true to life."
More like dumbness overrides "true to life." I'm pretty sure that falling down the stairs is funny to some people (which is what I did).
Other mistake: Buzzy said that Rob made a song making fun of Sergeant Foley. However, Rob's Sergeant was Lebost.
Dear Mrs. Petrie, Your Husband is in Jail - S3-E28
Character mistake: Rob is telling Laura why he's in jail. He says "Monica Doorwell! She must be Millie and Jerry's babysitter." The babysitter's last name is "Darwell". (00:02:00 - 00:04:00)
The Lady and the Tiger and the Lawyer - S3-E16
Continuity mistake: Donna goes back to the den to get her coat to show Arthur. Laura yells at Rob in the kitchen "Rob! Did you lock her in the Bathroom!?" It's a den in most of the episodes... Turns out in this episode it turns into a bathroom with carpet on the floor. (Supposedly when Laura is yelling at Rob in the kitchen).
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.
What's in a Middle Name? - S2-E7
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)
Suggested correction: Rob inherited the desk from his great-uncle, i.e. his grandfather's brother.
What's in a Middle Name? - S2-E7
Other mistake: The piano in this episode in the Petries' old house behind Sam Petrie is the same piano from Rob's new office.
What's in a Middle Name? - S2-E7
Other mistake: Rob and Laura's old house changes from episode to episode when they go back in time reminiscing. 1: Petries and Helpers are in Rob's old house the size of that house was a trailer sized house. 2: Rob was in the Army the house was the size of a small apartment.
Other mistake: The crew members behind the camera are talking to each other and taking pictures when Rob and Laura kiss, throughout the series in a few episodes you can hear the camera shutter sound.
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)
The Sick Boy and the Sitter - S1-E1
Continuity mistake: The door in the kitchen is wide open in one scene and then the next time Laura and Rob go back into the kitchen the door is closed. (00:07:00 - 00:08:30)
Revealing mistake: When the female witness is called to the stand, VERY obvious shadowing of the boom mic when she stands up - you can see it on the wall.
