Big Blunders In Iconic Shows That Slipped Past Editors


Television Mishaps That Aired

TV shows transport us into different worlds, but sometimes, reality crashes in at the worst moments. These slip-ups amused fans for years. But how do these blunders happen? More importantly, how many have you caught? 

Stranger Things

The Changing Apartment Numbers That Defied All Logic In Friends

Sitcom fans are known for their attention to detail, and this is why this Friends blunder became infamous. Monica’s apartment number used to be 5, and Chandler’s was 4. Suddenly, their numbers changed to 20 and 19, probably to reflect a high-rise setting. But eagle-eyed viewers never let it slide.

The People Of Westeros Had Their Own Starbucks In Game Of Thrones

In one of the biggest mishaps in TV history, Game of Thrones—a show known for dragons and medieval grit—accidentally left a modern-day Starbucks-style coffee cup in a scene. Yes, Westeros got its first latte! Maybe Daenerys needed a caffeine boost before burning down King’s Landing?

Chidi’s Accent Didn’t Make Sense In The Good Place

The Good Place had plenty of philosophical twists, but one inconsistency stood out. Chidi, a native French speaker, magically had a perfect American accent—even in flashbacks from his childhood in Senegal. The show later justified it by saying that he attended American schools.

A Crew Member Became An Accidental Extra In The X-Files

In a show packed with government conspiracies and alien encounters, you wouldn’t expect to see an ordinary bystander. Yet, in The X-Files episode “Paper Clip,” a group of random people, including someone with a dog, is visible in the background of a supposedly secret government site.

A Time-Bending Christmas Timeline Confused Fans In That '70s Show

“The '70s” apparently lasted a little longer than expected. That '70s Show supposedly covers four years, yet the gang celebrates five Christmases—a mathematical impossibility. Did Red Forman secretly invent time travel? Or did the writers just prioritize festive episodes over logical continuity?

Haley Dunphy’s Phone Was Upside Down In Modern Family

Phones in movies and TV shows often seem to follow their own rules. Take Modern Family, for example. In the episode "Rash Decisions," Haley Dunphy (played by Sarah Hyland) takes a call while driving—except there’s one tiny problem: her phone is upside down. Yep, full-on flipped.

Doug Ross’s Forgotten Son In ER Proved Even Doctors Make Mistakes

Dr Ross, played by George Clooney, once admitted to having a long-lost son he’d never met early in ER. Strangely, the show never referenced this child again, even when Doug started a family with Carol Hathaway. Was it an abandoned storyline or just a case of fatherly amnesia?

Captain Holt’s Medals Are All Wrong In Brooklyn Nine-Nine

A man as meticulous as Captain Holt shouldn’t have a uniform inconsistency—but here we are. Throughout Brooklyn Nine-Nine, Holt’s medals are usually in the wrong order. Although this is a little detail, a production consultant should have noticed it.

The Mandalorian Accidentally Included A Crew Member In The Star Wars Universe

A galaxy far away wasn’t far enough to keep this mistake out of sight. In The Mandalorian, during a tense scene in Chapter 12, a crew member is wearing jeans in the background. Fans immediately dubbed him “Jeans Guy” and turned him into a meme before Disney edited him out.

The Van In The Walking Dead Defied The Laws Of Physics

Car stunts are impressive, but The Walking Dead delivered one that defied logic. In one episode, Carol and Daryl’s van tips forward off a bridge, flipping nose-down—only to land perfectly upright on all four wheels. Even Fast & Furious would have had trouble justifying that landing.

A Disappearing Straw Confused Viewers In Mad Men

Period-accurate details were Mad Men’s specialty, but even Don Draper couldn’t smooth-talk his way out of this one. In “The Inheritance,” Betty Draper is seen drinking from a Coca-Cola bottle with a bright red straw. In the next shot, the straw is completely gone—then it suddenly reappears.

A Sunroof Reflection Revealed A Boom Mic In Frasier

Frasier Crane prided himself on class and sophistication, but even he couldn’t predict this slip-up. While standing up through his SUV’s sunroof, the back window reflection clearly shows a boom mic hovering above him. This high-brow sitcom wasn’t immune to production blunders after all.

A Murder Suspect Repeated A Scene In Law & Order: SVU Like A Bad Alibi

Nothing gets past Olivia Benson—except this editing mistake. In Law & Order: SVU, a suspect angrily storms off from an argument with Stabler. But in the next shot, he’s back at the starting point, walking away again, mouthing lines from the previous scene. Maybe it was just an advanced interrogation technique?

Pacey’s Birthday Changed Seasons In Dawson’s Creek

Time is fluid in Dawson’s Creek, at least when it comes to birthdays. In Season 2, Pacey celebrates his 16th birthday during the summer, yet in Season 4, his 18th birthday takes place in the middle of winter. Since Dawson’s Creek thrived on drama, maybe time just moved differently there.

A Television Antenna Appeared In 1912 In Downton Abbey

Historical accuracy was one of Downton Abbey’s biggest strengths—until it wasn’t. In one episode set in 1912, the show revealed a TV antenna on the roof of the Crawley estate, decades before television was even invented. The anachronism was quickly pointed out to become one of the show’s famous mishaps.

A Flashback In Friends Contradicted Rachel And Chandler’s First Meeting

Friends’ timeline was shaky at best, but one contradiction was too obvious. In the pilot, Rachel meets Chandler for the first time through Monica. However, in later flashbacks, we see they had already met multiple times in college. The writers probably hoped everyone was too busy laughing to care.

A Stunt Mat Magically Disappeared In The Mandalorian

Even the best bounty hunters need safety precautions. In The Mandalorian, during a fight sequence, a cream-colored stunt mat is clearly visible as Cara Dune throws a thug to the ground. A few seconds later, when the camera cuts back, the mat is gone.

Severance Couldn’t Keep The Time Right

Apple TV’s Severance has a mind-bending premise. However, in the very first episode, Mark (played by Adam Scott) wears a watch that seems to have its own severance program. One moment, the date reads 4. Then, suddenly, it’s 5. Then, like a glitch in the Matrix, it’s back to 4.

Will And Carlton Aged In Reverse In The Fresh Prince Of Bel-Air

In the early seasons of The French Prince of Bel-Air, it’s mentioned that Carlton is a year younger than Will. But later, both characters are treated as if they’re in the same grade. But let’s be real—if anyone could manipulate time, it was Uncle Phil making sure they graduated together.

A Baby’s Name Changed Without Explanation In Vikings

History is brutal, but apparently, so is continuity. In Vikings, Ragnar Lothbrok whispers to his unborn child, calling him Sigurd before he’s even born. Fast forward a few episodes, and when the baby finally arrives, Ragnar asks what the child’s name is, acting as if he had never chosen one.

A Wedding Contract Contradicted Claire’s Memory In Outlander

In Outlander, Claire claims that she doesn’t even know Jamie’s full name before their wedding. However, in a previous episode, she had already read their official marriage contract, which clearly listed his full name. Despite being a time traveler, she wasn’t great at remembering paperwork.

Timmy Forgot He Was A US Citizen In Rules Of Engagement

For a man who prided himself on intelligence, Timmy had a major lapse in memory. In Rules of Engagement, he agrees to a fake marriage with Russell because he needs a green card. However, two seasons earlier, he had explicitly stated he was already a naturalized US citizen.

A Car Window Reflection Revealed Crew Equipment In That '70s Show

Nothing breaks 1970s nostalgia like modern filming gear. In That '70s Show, during a scene in a hardware store, a shiny metal pot in the background reflects stage lights and part of the film crew. Fans with sharp eyes caught the mistake.

Sasha Repeated Girl Scout Cookie Sales In The Office

Toby Flenderson told the Dunder Mifflin crew that it’s his daughter Sasha’s first year selling Girl Scout cookies in Season 8 of The Office. The only problem is that he had already bought cookies from her in Season 4. Looks like Sasha had a delayed career in cookie sales.

A Flashback Scene Created Two Different First Meetings In Scrubs

Even best friends can’t remember everything the same way. In Scrubs, J D and Turk recall meeting for the first time as college roommates, with JD nervously introducing himself. However, another flashback shows Turk entering the dorm to find JD, who has already moved in and is wearing a wizard hat.

A Plane Passenger Appeared And Disappeared In Lost Without Explanation

Considering all the mysteries in Lost, this one was subtle—but baffling. In the pilot episode, a background survivor of Oceanic Flight 815 is clearly visible in the wreckage. A few episodes later, the same survivor completely disappears, never to be mentioned again. Has the island claimed another victim off-screen?

A Character Vanished And Returned As A Different Actress In Boy Meets World

Disappearing without explanation is one thing, but coming back as an entirely different person is another. In Boy Meets World, Cory’s little sister Morgan vanished for a full season, with no mention of her whereabouts. When she returned, she was played by a different actress.

Sam Malone’s Office Door In Cheers Changed More Than His Love Interests

In Cheers, Sam Malone’s office door was almost as inconsistent as his relationships. Sometimes, the frosted glass had "Manager" written on it; other times, it was mysteriously blank. No one mentioned the change, and the bar regulars never seemed to notice. Fans, however, did.

An Elevator Timeline Didn’t Add Up In The Big Bang Theory

The elevator in The Big Bang Theory became a running joke, but its backstory didn’t quite check out. In early seasons, Leonard states that it broke two years before the series began. However, later flashbacks of the event occur several years earlier. Fans realized the show had rewritten its own history.

A Crew Member’s Hand Helped With A Scene In

Behind-the-scenes assistance is useful—except when it’s in the final cut. In Three’s Company, Terri enters the kitchen carrying two cans, but a crew member’s hand sneaks into the frame to place a bag on the counter. It’s one of those classic sitcom bloopers that, once seen, can never be unseen.

A Rock-Solid Memory Gap Contradicted Vampire Lore In Buffy The Vampire Slayer

Vampires may be immortal, but apparently, their rules aren’t. In Buffy the Vampire Slayer, Angel claims that vampires don’t breathe, which is why he can’t perform CPR. However, throughout the series, vampires smoke, talk, and even get choked—things that require breathing.

A Forgotten Name Swap Turned David Into Kevin In Roseanne

Name changes happen, but usually not mid-series. In Roseanne, Darlene’s boyfriend was originally introduced as Kevin, but soon after, his name mysteriously changed to David. The show never explained the switch, though later on, Roseanne joked that Darlene had simply “decided” to start calling him David.

A High School Flashback Changed Phil’s Age In Modern Family

Even Phil Dunphy couldn’t joke his way out of this one. In Modern Family, a flashback shows Phil and Claire as high schoolers, revealing that Phil was a senior when Claire was a freshman. Nevertheless, earlier episodes had already established that they were the same age.

A Time-Travelling Family Photo Appeared In The Simpsons

For a show that mocks continuity errors, this was a funny slip-up. In The Simpsons episode “And Maggie Makes Three,” a flashback shows Marge and Homer in their living room before Maggie was born. Yet, there was a framed photo of baby Maggie clearly visible in the background.

An Unopened Letter Got Read In Gilmore Girls

Fast-talking dialogue wasn’t the only thing moving at lightning speed in Gilmore Girls. In one episode, Lorelai receives a sealed letter from Christopher and holds it unopened. In the next shot, she’s reading its contents without ever having opened it. Maybe Lorelai’s coffee addiction had granted her superpowers after all.

A Crew Member Became An Accidental Extra In Angel

During a fight scene in a nightclub in Angel, a camera pans too far to show a crew member holding a camera rig at the bottom of the frame. It became a funny example of how even the most polished shows sometimes let real-world elements sneak in.

Several Crew Members Were Seen In The Shield

The Shield is a popular 2000s show. However, despite its popularity, fans noted a few mistakes that probably happened due to the camera moving way too fast. For example, many crew members were seen in the pilot, although they weren’t part of the storyline.

A Forgotten Tattoo Moved Around Jack’s Arm In Lost

Jack Shephard had plenty of scars, but his tattoos were another story. Throughout Lost, Jack’s arm tattoo inexplicably changes size, placement, and clarity depending on the episode. While some blamed lighting and makeup inconsistencies, others joked that Jack’s ink was just as mysterious as the island itself.

Jerry’s Apartment Magically Redecorated Itself In Seinfeld

Kramer wasn’t the only unpredictable thing in Seinfeld. Jerry’s apartment layout constantly shifted. Sometimes, the hallway outside had doors leading to other units; other times, it led nowhere. Even the furniture moved around as if possessed. But since Seinfeld embraced absurdity, many just laughed it off.

Blanche Devereaux’s Birthday Changed When It Suited Her In The Golden Girls

Blanche Devereaux’s age was a well-guarded secret in The Golden Girls, but her birthday was an absolute mystery. Depending on the episode, she gave different dates, proving that vanity was stronger than consistency. Some viewers speculated she was deliberately lying, which fit her character.

A Modern Pickup Truck Drove Through The Virginian

Set in the 1890s, The Virginian prided itself on historical accuracy—until a Chevy pickup truck made a surprise appearance. As a character rides away on horseback, a very 20th-century vehicle is visible in the background. Considering how long Westerns dominated TV, a stray truck was bound to sneak in eventually.

Time manipulation is expected in Doctor Who, but not by accident. As the Doctor rushes around Amy’s house, a clock in the background is running backward—and not because of any wibbly-wobbly timey-wimey explanation. People debated whether it was a hidden Easter egg or an overlooked production mistake.

Fast forward to Season 4, and no one—including his own mother—mentions it when that exact date rolls around. The creators admitted they simply forgot.

Apocalyptic survival is tough, but apparently, some walkers had access to modern footwear. In The Walking Dead, a background zombie can be seen wearing very non-decayed Nike sneakers, blending in just a little too well. Given the show’s grim attention to detail, this mistake stood out.
