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.
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.
Other mistake: The record that is to Rob's right (our left) isn't spinning while the base part under it is, until Rob puts the ceramic coffee cup on the record. Notice that ceramic coffee cup is also the same coffee cup that Rob threw away in the episode "Your Home Sweet Is My Home"
Suggested correction: So you are claiming that they somehow rigged the turntable so it would spin without spinning the record until he put the cup down on it. For what reason? No only does this error defy common sense, it is obviously wrong if you watch the episode. The record is spinning. You can see the variations in the highlights on the surface as it does so. Also, it is not a ceramic cup, it is a paper cup, complete with a folding paper handle. And it in no way resembles any cup used in "Your Home Sweet Home is My Home."
I did great! I forgot which episode I saw the same cup in.
Happy Birthday and Too Many More - S3-E15
Other mistake: Laura is doing some work on when to have Richie's birthday, and Rob tells Laura "I thought we decided that about 8 years ago." Yet Mrs Billings has asked Rob to do 2 plays (1 each year for the PTA meetings) In the Happy Birthday... (Feb 1964) episode that would have made Richie about 10 due to the fact that Richie was 8 when "What's in a middle name" (Nov 1962) aired. (00:01:00)
The Ballad of the Betty Lou - S3-E9
Other mistake: While Jerry and Rob are furious, Jerry asks the sailor "What's the matter with the lights?" and the sailor says "power failure on the line, they can't locate it." If there's a power failure then the room would be completely dark just like it is outside. Yet Rob and Jerry have shadows on their hats, jacket, shirts etc. as well as a shadow from the bunk bed. These shadows are caused by the non-working lights or the lights behind the camera.
What's in a Middle Name? - S2-E7
Deliberate mistake: Rob, Sally and Buddy's "old office" is exactly the same shape as Robs basement (except for the door in the center of the back wall. Instead of going upstairs it's all on 1 level. There's a door to the right which goes into a random room which we never get to see inside). (00:10:38)
Suggested correction: Since you listed multiple differences, it's obviously not "exactly the same." Filmmakers not building every set and prop from scratch is not a mistake. Modifying and reusing old sets is just an economic reality of production. If anything this should be under trivia.
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.
The Great Petrie Fortune - S5-E6
Revealing mistake: The great-grandfather Petrie was just Rob Petrie dressed as a really old man. The lamp in the movie is also one that has been in Robs house and Sally's house in a few of the episodes.
