** In "Barn Burner", Randy suggests that he and Darnell from a moped gang called SaltAndPepper, [[DiscriminateAndSwitch because they both like salt and pepper on their French fries]]. In later episode "Little Bad Voodoo Brother", Randy says that he can't taste salt due to ingesting bleach as a result of Earl's mean-spirited pranks in their youth.

* ''Series/MyNameIsEarl'':

** Like Catalina, Nescobar A-Lop-Lop, who was being taught English by Earl in "Teacher Earl", is speaking decent English in all flashbacks.

** The Hickey brothers didn't know Joy until Earl married her and Catalina until after Earl's karmic revelation. All the flashbacks make you wonder a little why they didn't know Joy most of their lives and Catalina during the six years she had immigrated to America, as both seemed to be regulars at the Crab Shack.
** Speaking of Catalina, she told Earl in the early episode "Teacher Earl" that she only learned English a year ago. Nearly all flashbacks feature her speaking fluent English, and the ones that don't take place either before or just after she immigrated to America. Additionally, in "South of the Border", her uncle and brother can speak fluent English even though they've never been to America, making it less likely that Catalina wouldn't know English before immigrating.

** They established that Earl married Joy in November (six months pregnant with her son Dodge) and they had a [[MillenniumBug [=Y2K=]]] adventure for their first New Years together. The last episode showed that Dodge was conceived on Halloween...

** In "Made a Lady Think I Was God", Darnell says that Mr. Turtle doesn't have a first name (with Randy naming him "Randy"). In "Got the Babysitter Pregnant", Darnell buries a turtle he thinks is Mr. Turtle (Joy lost the real Mr. Turtle and got a replacement that died) and the headstone reads "Mr. Sydney Turtle". It's possible that Darnell gave him a first name later.

** In season four, Darnell's WitnessProtection cover is blown when he is caught on camera trying to restrain Joy from beating up Brian Dunkleman during the ''Estrada or Nada'' tryout. Darnell had appeared on TV at least three times before this, in both of the ''Series/{{COPS}}'' episodes and in "Boogeyman" where Earl had accidentally been implicated for kidnapping Albie, yet his cover somehow wasn't blown. The latter can be handwaved due to it only airing on the local news, but ''COPS'' is broadcast nationwide.

** Speaking of Catalina, she told Earl in the early episode "Teacher Earl" that she only learned English a year ago. Nearly all flashbacks feature her speaking fluent English. Likewise with recurring character Nescobar A-Lop-Lop, who was being taught English by Earl in the same episode.

** In "Cost Dad the Election", Earl says he's allergic to cats. In "Larceny of a Kitty Cat, it's ''Randy'' who is allergic to cats.

* ''Series/InterviewWithTheVampire2022'': In the fifth episode, the gravestone commissioned by his sister Grace establishes that Louis de Pointe du Lac's birth date is Oct. 4, 1877 (which must be the correct year because he was 33 years old when he was turned into a vampire in late 1910), yet in the seventh episode, he informs several would-be victims that he was born in 1878.

** Plus there's how old all the Friends are, Season 1 has Monica and Rachel say they're 26, and Ross, Chandler and Joey are 27. (Phoebe is murkier). However by Season 7 Monica and Rachel are 30, and the guys are 31, making them 24 and 25 in Season 1, which is supported by flashbacks of the dates they attended high school/college. It looks like in early seasons the writers planned for the characters to be older, realized it didn't work and lopped a few years off everyone's ages. Or a Tv seasonin our time does not equal a year in show time.

** In another episode, Sheldon asserts that he never forgets anything. Later in the same episode, when he is listing all of the actresses who have played Catwoman, Howard points out that he left out Lee Meriwether. "Oh. I forgot about Lee Meriwether". Unfortunately, it doesn't appear that the writers caught the joke. {{Justified}} as Sheldon is known for massively overestimating his own intelligence. [[note]]He also forgot Maggie Baird, who played the role in ''Series/BirdsOfPrey2002'' for all of one scene, but that one's presumably on the writers.[[/note]]

** Pam Beesly has had her name in various incarnations spelled Pam Beasley, Pam Beesley, Pamela Jean Beesly, and the now-canon Pamela ''Morgan'' Beesly.

** In the pilot episode, Dean tells Sam he hasn't spoken to Sam in two years. Since Sam is in his senior year at Stanford, this suggests the boys had contact while he was at college. However, later episodes seem to indicate that the boys have been separated since Sam left home to go to school. It's possible there was some phone contact or something, but this would have been significant and is never addressed. It's more likely a mistake that was retconned.

*** Within ''Big Bang'', season one suggested that George Cooper had only recently passed away (Missy brings documents from George's estate for Sheldon to sign and when Mary seduces Dr. Gablehauser to get Sheldon his job back, Mary says George has been dead "long enough" implying it wasn't really that long. Also, in "The Pancake Batter Anomaly", Sheldon said at the age of 15, he got sick in Germany, and his mother had to fly back to Texas to help his dad at that time.) but later episodes established that Sheldon was 14 when his father died, over a decade before the first season. George is also described posthumously as being an abusive, idiotic, misogynistic, drunken redneck whose constant fighting with Mary traumatized Sheldon to the point where he cannot stand to hear arguing of any kind. ''Young Sheldon'' portrays George as your average BumblingDad who treats his family well despite the occasional petty squabble.

** In the ''TNG'' episode "[[{{Recap/StarTrekTheNextGenerationS6E4Relics}} Relics]]", Scotty is released from a transporter buffer where he was trapped for hundreds of years and initially believes that Geordi and Riker were sent by Kirk. However, ''Film/StarTrekGenerations'' reveals that Scotty was present when Kirk was sucked into the Nexus from ''Enterprise-B'' (this was due to Scotty being placed in the movie at the last minute since Creator/LeonardNimoy wasn't available). The ExpandedUniverse attempted to {{Retcon}} this by saying that Scotty never really believed Kirk was dead.

* ''Series/LazyTown'': Between the first and second episodes. The former implies Sportacus is a newcomer: the previous hero wore a "9" whereas he wears a "10"; Sportacus says he's heard of LazyTown but still had to research it; Robbie Rotten shouts "Another one?!" when he first sees him; and Sportacus formally introduces himself to the townsfolk at the end. The latter, however, states that Sportacus taught everyone to play baseball the year before.

** When Hodges breaks up with Elizabetta, the Italian woman he nearly married in a later season of the original series, part of the reason he panics is she wants to move back to Italy and have kids. But in the 2021 revival, Hodges has a wife who’s pregnant with their kid and the season ends with the baby’s birth. People do change their minds about kids, ut it still feels like an error to some fans.

** Sara was stated to have a brother, then later said she was an only child.

** Flack only mentions his mother and a brother once early in Season 4. His *sister* shows up in the Season 5 finale and pops in and out for around three years. Their conversations about their father and a few flashbacks to their childhood imply that the man had raised only the two of them after their mother's death.
** Stella told a character in a Season 1 ep that she lived at St. Basil's orphanage until age 18, but in Season 3, an ep aired with a big plot point being that Stella lived with a foster sister who was molested and eventually killed her attacker, and that the two of them were so close they became [[BloodBrothers blood sisters]]. In Season 6, this is retconned that her mentor had "rescued" her from foster care and took her to live in the orphanage.

** Christine's late brother, who was Mac's friend/partner, was "Stan Whitney" officially but was called "Stephen" by her during a flashback in her first episode.

** In general, the show has even come up with an in-universe explanation which can act as a general retcon whenever needed; the Time War has just gone around screwing with the timeline! Whole events have literally been wiped out of existence (unless you're a time traveller, because then you can remember them).

** Several items that were on the official CSI website character bios were changed in onscreen canon, like Catherine being from Bozeman, MT (later given to CSI NY's Lindsay instead) and Grissom's father being involved in smuggling.
* ''Series/{{CSI NY}}'':
** The writers forgot names several times. Don is Don Flack Jr. originally, but when his father was discussed, he wasn't referred to as Don Flack.
** Stella told a character in a season one ep that she lived at St. Basil's orphanage until age 18, but later, an ep aired with a big plot point being that Stella lived with a foster sister who was molested and eventually killed her attacker. Unless she was just in and out of the orphanage.

** Danny was originally from "a family of cops", later stuff contradicts that for the most part. The writers retconned that it was extended family, but not all fans buy it.
