Other mistake: Laura and Rob do not like having guns in the house and Laura is terrified about having them in the house... Yet in this episode... There are 2 guns in the basement displayed right next to a giant deer head on the Cross beam in the middle of the room up high. Neither of them care that the guns are there.
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).
My Husband Is Not a Drunk - S2-E6
Other mistake: If Rob is that easily hypnotized then when Rob's friend hypnotized Millie he would have gone out light a light same when he did Laura and Jerry. Rob would have been out right then and there for all 3 of them... Not just when he did Buddy.
The Sound of Trumpets of Conscience Falls Deafly on a Brain That Holds Its Ears - S3-E11
Other mistake: Rob is complaining to Sally and Buddy about this couple running through a parking lot not looking where they are going, and they knocked him down on his rear end as well as hands. He fell into some grease yet there weren't any grease stains on his jacket which would have actually been on his butt and hands.
Fifty-Two, Forty-Five or Work - S5-E13
Other mistake: Right at the beginning of this episode Rob says "9 years ago right in this office... I just came on as head writer 2 months was all... Buddy, Sally and I were sitting at this desk, writing a sketch, and you (Mel) came in with some special news." (so on and so forth with that line.) Rob, Sally and Buddy weren't in "this office" building... Didn't even have the same desk or furniture.
Long Night's Journey into Day - S5-E23
Other mistake: Rob tells Jerry to keep calling Rob's house. Jerry says "hello, this is Jerome Helper" yet there was the episode "All About Eavesdropping" where Rob calls Jerry "Gerald."
Other mistake: Sam tells Rob "Laura could be late because of the rain". Yet neither Sam, Laura, Millie or Clark had any wet clothes, jackets, hats etc. Rob was the only one that had gotten soaking wet. Also when looking into the window he taps on the glass with a white glove (which he didn't have on when he got into her house).
Other mistake: Millie tells Laura (in the USO women's house) "I can't keep a boyfriend" yet she's been "married" to Jerry and they get along somewhat OK.
Love Thy Other Neighbor - S5-E29
Other mistake: Laura tells Rob that Jerry is fixing the fence. Then all of a sudden this banging that sounds like an iron hammer and chisel on cement starts up. If Jerry was actually fixing the fence it would have been the whole time, right when Rib got into the kitchen, not right after Laura told Rob that Jerry was working on the fence.
Long Night's Journey into Day - S5-E23
Other mistake: Millie tells Laura "I never sleep in my house alone!" yet Millie has been home about 2 or 3x by herself. In other episodes. Like when Jerry goes out of town usually.
The Life and Love of Joe Coogan - S3-E17
Other mistake: Rob is discussing the box of love letters with Laura she tells him "they're by the furnace!" Rob tells her "there's no shoe box by that furnace." Laura tells him "they're right behind some loose bricks" well when we see the basement... There's no furnace or bricks anywhere to be seen.
Other mistake: Laura tells Rob "oh you don't smoke!" But in several (double digit) episodes Rob not only has a lighter but also a cigarette in his hand or mouth. One episode while he and Laura are illegally about to eavesdrop he puts out the cigarette on the speaker causing the speaker to turn on and they start eavesdropping again.
Other mistake: That mirror behind Rob at the hotel in their room has fog (condensation) on it which means that the humidity there in "Mexico" is really really high or it's over 100°F in their room with humidity or unless it was raining inside their room, the window behind the bed is perfectly clear. (Real life that mirror would not be all foggy.) Also Rob, Laura and the hotel guy would have been sweating up a storm if it was really really hot out there. Which it wasn't. (00:13:52)
Other mistake: After Lyle gives back Rob and Laura's watch's and the $51, Rob doesn't get his ring back.
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.
A Nice, Friendly Game of Cards - S3-E18
Other mistake: With the way everyone was holding their cards, there is no way Rob could have been reading the back of everyone's cards.
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.
The Brave and the Backache - S3-E19
Other mistake: When Rob goes into the office of Dr. Philip Nevins there's smoke rising from the ash tray on his desk. Throughout the scene nobody's smoking.
