My favourite gaff is the "Blue Blazer Black" line from Friends. The fact that everyone continued to tease Matthew in character makes it doubly hilarious.

So the reason Phoebe was magically in a different spot in that scene was because there were more lines after she mentioned her eyelashes. Phoebe had walked over and sat down, and Paul was actually looking at someone else talking at that moment. They cut those extra lines for the aired version, but you can see the whole scene where she goes to sit down on the DVD version.

In an early episode of Designing Women Charlene calls home and asks how her siblings are and when Jan Hooks joined the show as her sister, she had a different name than the siblings Charlene mentioned.

In the Big Bang Theory, the guys plan to spend three months at the Magnetic North Pole. They meant the Geographic North Pole. The Magnetic Pole is constantly moving. Having spent some time near the Geographic North Pole in Greenland, I picked up on that immediately.

My favourite mistake in That 70's show is the fact that Eric is 17 for like 5 seasons and in that time there are I think two Halloweens

Someone already explained the Friends "mistake". But I also wonder if you could even see Phoebe in the original aired episode? Back then, screen ratio was 4:3. When everything shifted to 16:9, a lot of mistakes were then seen of things the camera caught that were left in because it was cropped off by the 4:3 ratio, so they didn't waste the time fixing it.

Fun fact: the actor who played the ugly version of Jackie in Kelso's fantasy (at around 0:52) is Carlos Alazraqui, aka Garcia on Reno 911, Rocko on Rocko's Modern Life, Clam on Camp Lazlo, Spyro in the first Spyro the Dragon game (his Rocko's Modern Life costar Tom Kenny took over the role starting with the second game) and he was the voice of the Taco Bell Chihuahua.

Very minor mistake: In one BIG BANG THEORY episode Raj says to Penny "Wasn't it [Shakespeare] who said "It is better to have loved and have lost than have never have loved at all?". The answer, Raj, is No. That was Alfred Lord Tennyson

Golden Girls had quite a few errors. There were 2 different Glen O’Briens with different back stories and played by different actors. The one thing they had in common was a romantic relationship with Dorothy. Rose’s daughter Brigette is just in the one episode and never heard of again. She vanished after going to England. Another daughter of Rose’s, Kiersten, was played by two very different actresses and with slightly different back stories. In the first season, she comes to Miami. She’s tall, has short blonde hair, was very fashionable and had no accent. She also has a daughter (Charlie) who looks around 8 years old. A few seasons latee, we see her again. She’s petite, has long brown hair and dresses more country. She mentions having kids, but all were too little to travel. Blanche’s daughter Rebecca had a very similar treatment. We meet her early in the series and she’s obese with short blonde hair. She appears again in later seasons, taller, with long curly brown hair. Originally she was a former model but no mention of modeling when she reappears. And the biggest plot hole of them all! Coco. He’s a live in cook and housekeeper, but only in the pilot episode. He just vanishes in the second episode and there’s never any mention of him.

Your list focuses on more current shows, but on "I Love Lucy, " Ethel Mertz had three different middle names - Ethel Louise, Ethel Mae, and Ethel Roberta were said over the course of the series.

I feel like I remember them talking about the Phoebe thing and it was that they didnt have a reaction shot so they used one from later on and it being in a smaller aspect ratio she wasnt seen in the original run but when they were remastered and started streaming the aspect widened and things were more noticeable, like that and the times when they used over the shoulder stand ins because before you would only see a shoulder and a little hair, now you see a whole side of a face and a Monica one was REALLY noticeable.

Number one is my favorite sitcom of all time friends

Amazing tv mistakes in sitcoms, fantastic job ms mojo on the video.

[terricunningham]

my 1st thought was the Cosby show...in the first season they talked about having only 4 kids and then later episodes they talk about all 5 kids.

[kareneastman]

That captain in Brooklyn99 was lying about not having a tv in his bedroom.The nail polish mistake in The New Girl is weird.😲

8:26 - last nite I caught a rerun of the Big Bang where they all contribute $$ for a prop from The Time Machine. In a later scene Steward as called "Dave"!

[GODDESS]

I have 1 for you, Brady Bunch, early in the series Halloween episode they claim to not have an attic to have pulled off a particular prank but a season or so later Greg and Marsha are in fact fighting over who gets to have their own room in the attic. Check it out.

Full/Fuller House. Not only did Uncle Jesse’s last name change, but Kimmy’s siblings kept changing too. I feel like there was an episode where it said she was an only child or had sisters (??), then another episode where she said she was glad her parents stopped having kids after her, she had mentioned more than once having an older brother, then of course we meet her younger brother Jimmy on Fuller House

Honestly, two Phoebes would always be a good thing.

I have watched Friends a billion times ! HOW DID I NOT SEE THAT ?!
