Plot hole: When Dominique is on TV, she says she got the shoes from Al's store. Then the Amish guy comes out to confirm she broke her leg from the shoe he made. Al says yes. She got the shoes way before Al knew he had no more shoes and before they even hired the Amish guy. How can she break her leg from his shoe if he wasn't hired and making them yet?
Suggested correction: Al was passing the blame.
The correction above is correct.
How Bleen was My Kelly - S10-E5
Continuity mistake: The family assumes Fox Viewing positions suggesting they are using an antenna to get reception. A few episodes earlier, Al changed their cable television channels to all men channels. You don't need antennae if you have cable.
Suggested correction: Cable and antenna isn't an either/or situation. You can have cable but still use an antenna to get a local channel if your cable provider doesn't offer that station.
Plot hole: Al comes home from work. He purposely doesn't look in the kitchen, so he can act like he's surprised it isn't Peg that brings him a beer. Steve talks and Al acts surprised that he's there. When you walk in the front door you automatically see the kitchen.
Suggested correction: It's quite possible to do this. My house has a similar layout: front door opens into the living room, and the kitchen is at the back of the living room. I can come inside and walk to the couch without paying attention to the kitchen. Plus, Al is cranky after work - he says "Ah, what a day" - and he is focused on getting to the couch and relaxing.
This is the only episode where Al does this... Just because he knows it's Steve and not Peg. Pretty obvious.
Just because something is only shown in one episode, that doesn't mean it has never happened before. And because he said "What a day", it seems that his work day was especially frustrating, busy, etc. It's reasonable that he could focus on getting to the couch, not bothering to look at the kitchen.
Factual error: Al gets hired as a bartender despite having no liquor license and not having taken the course required to become a bartender.
Suggested correction: Depending on the bar all you need is a diploma or GED and be old enough per the state's laws.
Deliberate mistake: Why would Al have his Polk High football uniform in England?
Suggested correction: Al cherishes his memories as a high school football player. It's quite possible that he takes the uniform with him on some trips, especially when going to another country. I've known people who do this with items that are important to them; i.e. a jewellery box or a favourite picture of family. They feel better keeping the item with them, in case something happens at home while they are away.
Plot hole: In this episode Al is about to break Puggy Weaver's record. Peg decides to bowl and scores a perfect score of 300. Problem is Peg is a horrible bowler, as seen in season 2 episode 9. She never bowls with Al or even enjoys bowling, so this episode really makes no sense.
Suggested correction: This is not a plot hole, but a plot point. Yes, Peg is a horrible bowler, but it's typical Al Bundy luck that his wife would be able to put together a perfect game no matter how unlikely.
So this one and only episode she scores a perfect game? Highly unlikely. Oh and she's wearing a long evening dress too which would make it difficult to bowl. So this episode makes no sense.
It makes perfect sense. In the world of the show, the universe is out to screw Al over. The worst that can possibly happen to him will happen no matter how unlikely.
It is a comedy, so having all those "strikes" against her, she still managed to bowl a perfect game - leaving Al hopeless and hapless.
Factual error: It seems unlikely Steve's bank or any bank would leave its vault open at night as they close around five or six.
Suggested correction: Steve is the bank manager and is closing up for the day. There is also a security guard sitting right by the door. And he has to unlock the door to let Al in. No mistake here.
The mistake is about leaving the vault door wide open instead of closing it. Not about Steve needing to unlock the front door to let Al in.
My point is Steve is closing the bank with a security guard there and the door is locked. So what if the vault is open? Steve just hasn't closed it yet.
Master the Possibilities - S2-E16
Factual error: A credit card company doesn't send random cards to just anyone. One comes for Buck. First of all you need a social security number, proof of income etc. And looking at what Al and Peg bought, it's an unlimited card.
Suggested correction: Decades ago (including the 1980s when this show aired), credit cards were sometimes sent to almost anyone - or "anything", such as a family's dog. People used to joke about actually getting a credit card for their cats, dogs, infant children, etc. Credit card representatives also went on campuses to lure "unemployed" students into getting credit cards by offering a free gift. They hoped college students would buy what they wanted or needed and parents would bail them out (pay the bills).
Suggested correction: It should be pointed out that credit card companies, especially in the past, do send out random cards (and offers). They buy customer information from stores from various sources, like warranty cards. People who have received credit cards for their pets (which has happened) have often filled out warranty cards with their pets' name but the rest of the information is the person's.
And some of the "less than honest" recipients of unsolicited credit cards were able to use the cards practically immediately, so went on shopping sprees and charged thousands of dollars for whatever they wanted with no intention of paying or being identified. And not all college students had parents that would bail them out, resulting in huge losses. It took a while, but the credit card companies learned from their mistakes and made drastic changes to avoid getting ripped-off in the future.
Factual error: The final scenes titled "Kankakee 1991" show desert scenery in the background; Kankakee, Illinois is in the Midwest US, which is almost entirely grassland and no desert.
Suggested correction: Kankakee and most areas surrounding have sandy soil and some areas can look very desert like during a very hot dry season but the mountain in the background is what gives it away. Kankakee is very flat other than the landfills.
