Character mistake: Janet is waiting for Larry to deliver her new car and states to Jack that this is her very first car. But 5 episodes earlier in S8-E13 "Itching for Trouble" when Moose asks if they had a football that needed air, Janet says no, but one of the tires on her car are low.
Trivia: In the episode where Janet asks Jack if she's a bad kisser, take a look at Janet when he kisses her. Jack unexpectedly slip Janet his tongue (which surprises the audience as well) and that throws Janet off and shocks her. Her surprised face is not acting, and was really surprised he did that. You'll also notice that when they part, she can't keep a straight face.
Suggested correction: This does not happen, their kiss is closed and for 2 seconds and Janet doesn't ask about her kissing. She says before the kiss when they have few mishaps trying to kiss before the final kiss that no-one has ever picked her kissing before and his response was, "Just shut up and kiss me!" She responds, "Okay fine!" Then they kiss, mouth closed just lips.
Other mistake: In the Regal Beagle, Jack addresses Marsha as Ms. White although later in the episode her last name is revealed to be Whitewood. In addition, how could Jack have known her last name anyway? Marsha only said her first name in front of Furley and the trio early in the episode and presumably she hasn't talked to the trio since she left with Furley out the door.
Suggested correction: In addition to the other correction (occurring 00:07:25), this correction addresses the second part of the mistake, as to how Jack knew Marsha's last name. Earlier, when Larry tells the trio that Furley was fine with him being late with the rent, Janet states, "He's been wining and dining her for 3 days" (at 00:06:15). So at any time during those 3 days (offscreen), Furley told the kids about his dream girl, which would have included her last name.
Suggested correction: No Jack does say, "Hello Ms. Whitewood!" While they are shaking hands. Time stamp in the episode when this occurs is at 7:25.
Lee Ain't Heavy, He's My Brother - S4-E21
Character mistake: Jack's older brother Lee comes for a visit. In the second season when Jack's Uncle visits, both make note of Jack being his only nephew. Lee would be his other nephew.
Suggested correction: Although it's not stated in the show, theoritically speaking, it WOULD be accurate if Jack and Lee were HALF-brothers (with same father since both last names are Tripper) and Fremont was the brother of Jack's mother, then Jack COULD be his only nephew as Lee would have NO relation to Fremont.
I submitted the above correction based on a theory that would make it possible, although in reviewing one of the scenes involving Jack's Uncle, I realise this would not be the specific case. Uncle Fremont most likely is the brother of Jack's father (not mother like the theory) due to the fact when he tells Mr. Roper that Jack's father is happily married but that doesn't stop him from having "fun" with a friendly nudge. He most likely would not say that if it was against his own sister. So yes, the theory didn't apply in this specific situation. Instead, the situation here is during the Roper early seasons, the episode came out with the Uncle and a year or two later (during the Furley era) Lee was intruduced. Neither were ever mentioned in any other episode so it could be simple inconsistent screenwriting.
Plot hole: Janet and Chrissy accuse Jack of making the fake BBQ telegram. However, Jack was at The Apartment the whole time, never left once until after he found out Lori was the one who made the telegram. If it was Jack who made the fake telegram, he would have had to leave The Apartment to do that.
Suggested correction: True, there's no logical way that Jack could have sent the telegram. But Janet and Chrissy were upset about it - when someone's upset, they don't always think in a logical way.
Or he could've called Larry and had him set it up but I don't think he ever used the phone to call anyone.
Continuity mistake: In episode 8-3, they got a new couch. In this episode, the old couch is back. (00:05:01)
Suggested correction: Many episodes in Season 8 were aired out of sequence from how they were actually filmed. The production code for this episode was 801, and the code for the episode where they got their new couch was 804 (made 3 episodes later - even though it was actually aired first).
Character mistake: When Felipe thinks Jack proposed to his cousin Maria, Felipe is happy and congratulates Jack. Later in the episode though, Maria's fiancé shows up and Felipe is shown as already knowing about him. Why wouldn't Felipe tell Jack that Maria was already engaged instead of showing happiness of Jack's "proposal"?
Suggested correction: You missed the entire plot of the episode. Maria's fiancé broke off the engagement, so she went to Felipe's. Then, when he thought Jack had proposed, he was happy. But Jack thought he was happy for offering her a job. Jack then begins talking about Maria as an employee (like trying her out in the kitchen and getting someone to train her). But Felipe thought Jack meant those things about Maria being his wife and got mad at Jack. Then told Jack he's not marrying Maria.
Character mistake: When Jack is tending bar, the one woman states margaritas don't include tequila, when it's the primary liquor.
Suggested correction: This is from s02e10, "Stanley Casanova." However, she doesn't say margarita, she says daiquiri, which is what Jack made with tequila. Daiquiris don't contain tequila but typically rum.
The Not-So-Great Imposter - S5-E9
Plot hole: All these characters (the bookie, policemen, the sister, the husband) were after David Miller and all come to attack Jack in some way (thinking Jack is David Miller). However, a big city like LA most likely has several David Millers so why would they all assume this David Miller is the one they're looking for? So even though Jack's name could have been David Miller, how would everyone think he is the one they're looking for?
Suggested correction: These are questions, not plot holes. First, Jack and the restaurant are in Santa Monica, not LA. At the time, Santa Monica had a population of around 88,000. While the article was printed in the LA Times, there wouldn't be a lot of famous, professional chefs, working/living in Santa Monica named David Miller.
Factual error: In this episode, Jack asks Felipe how he can bring Mr. Angelino to The Apartment, in which he answers "We took the Santa Monica freeway to the Cloverfield exit." The Cloverfield exit is in reality, a good 2 miles or so from the beach (2 other exits are much closer to beach than this). Yet throughout the series, it is implied that The Apartment is very close to the beach (3 blocks is stated by Jack in a much earlier episode). Why a far exit for a beach-area apartment?
Suggested correction: Correcting my own entry: I just recently saw this episode for the first time in a long time. Felipe actually says the "Centinela" exit (not "Cloverfield"). Technically this even adds to the mistake as it is one exit even FURTHER from the beach area apartment. Now 3 miles away exiting (instead of 2 as previously submitted).
Revealing mistake: When Chloe (the new hire) and Janet are talking on the couch near the end, water spots suddenly appear on Chloe's shirt, indicating the actress was lactating while filming.
Suggested correction: Just because it was never mentioned in the storyline of the show, there is no reason Chloe couldn't have a baby at home thus causing the lactating.
Sorry, but the wording in this correction is confusing. Agreed, there was no mention in the show of Chloe having any baby at home. So very well, she may have been lactating, which explains the sudden water spots as mentioned.
Suggested correction: It could have been a quick comeback line as a joke. The way Janet was even saying it sounded that way. Also, technically speaking, she did have a car in the past. The trio had bought Roper's Car for a very short time (from an earlier episode) before Roper bought it back from them. Janet never physically drove it but at that time, she was ⅓ owner of it so technically she had a car before.
Yes, I always thought it was a quick comeback.
