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 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.
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 Life and Love of Joe Coogan - S3-E17
Other mistake: When Rob, Buddy, Sally, Joe and Mel are all showing up after they played golf at the beginning of the episode if you look at the window all the background there is flat as heck. But trees do not increase in elevation that quickly in flat ground. Unless you're in the mountains.
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.
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.
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.
Honeymoons Are for the Lucky - S3-E22
Other mistake: Rob is in Captain Lebost's office. Rob has already said that Laura accepted his proposal weeks ago and they got married 2 weeks ago, and he asked for 1 3-day pass. Yet in "Will You Two Be My Wife?" he says he asks for 2 3-day passes so he could go get married.
