Remember when Michael hit Meredith with his car by accident in "Fun Run" on season four? As a result, her pelvis got fractured and she had to get a cast. It was in "Launch Party" when she asked Jim to sign it for her (not awkward at all...). But as he signed it, he pretty much broke character and signed his true name, "John Krasinski." If you looked at the scene closely, he dotted two i's, even though there's only one in "Jim Halpert." Plus, the big K in his last name is pretty obvious.
Or in other words, the role was randomly recast after season two. Actress Shannon Cochran made her appearance as Pam's mom, Helene, in "Sexual Harassment" (and her character briefly dated Michael). But when Helene returned for her daughter's wedding on season six, the role was played by Linda Purl. Only fans with great memory might have noticed this change. But it turned out that Shannon couldn't return to reprise her role because she had other commitments. Considering that she appeared on the show over four seasons prior, it's understandable that she already moved on to something else.
The Bernards made their first appearance when Andy proposed in Angela on season four. As it all happened during Toby's Goodbye party, he briefly mentioned his parents and referred to them as "Andrew and Ellen Bernard." Then, the camera cut to his parents proudly watching along and waving.
However, during a later episode, he referred to his dad as "Walter." He also explained how his name got switched from "Walter Jr." to "Andrew" because his parents thought his brother would better represent the family name. On top of the name change, both of the actors who first appeared as his parents were replaced by completely different actors on season eight. Even worse, Andy's dad was played by Stephen Collins, a sexual predator.
At first, Angela mentioned that she had only one sister that she never kept in touch with. Then, as she and Dwight were planning their wedding, Dwight commented on how much time it would take for each of her sisters to give their speech. At said wedding, though, Angela went back to having a single sister. And oddly enough, they were suddenly super close. This completely contradicted her initial story, since she explained that they had a huge fight and hadn't spoken to one another in years.
On season three's "A Benihana Christmas," there was a scene where Michael rode a bike with ease into the office. But on season seven's "The Sting," he suddenly had no idea how to ride one and he had to be taught. It's kind of odd because bike-riding is the kind of skill that sticks with you after you've already mastered it. But we're guessing that the writers completely forgot they already created a scene with him riding a bicycle to donate to charity.
On "The Secret" from season two, Jim told Pam that he developed a crush on her when she first started at Dunder Mifflin. But then during season four, Jim said that on his first day of work, Pam was the one who walked him to his desk and warned him about Dwight. This contradiction was never addressed and the real story about who really started first was never revealed. So what we're still wondering is this: Who was telling the truth here???
On the episode "Job Fair" from season four, Pam revealed that she used to pretend she had PMS so she wouldn't have to play volleyball. But during the company picnic on season five, she played the sport so well she looked like a pro. She also said: "Maybe I played a little in junior high. And in high school. Maybe a little in college. And went to volleyball camp most summers!" Fair enough. Except for the fact that this explanation directly contradicts what she said on season four.
It's easy to miss this one because Nick was a minor character that only appeared on a few episodes. He first appeared on "Job Fair," where he met and spoke with Pam from a Graphic Design booth. But later on the series, he became the IT guy at Dunder Mifflin. Yes, it is possible that he was skilled at both, but even that seems like a stretch because IT and graphic design are two completely different fields. Perhaps the writers just thought that viewers wouldn't really take notice of this detail.
On the "Pool Party" episode from season eight, Oscar (played by Oscar Nunez) got completely drunk and declared himself the "god of wine." But in one particular scene, where he was seen drinking straight from the wine bottle, a label with his name on it was clearly visible on the bottom. It was a pretty harmless and minor mistake, but honestly, we still can't believe we missed this one the first time.
During the first season's "The Alliance" episode, Michael asked Pam if there were any upcoming birthdays. She responded that there weren't any, but that Meredith's birthday would be in the following month. However, in "Survivor Man" from season four, Angela revealed that Creed, Oscar, and Meredith all shared birthdays in the same month (with Meredith's being at the end). Maybe Pam had the wrong information or she intentionally lied to Michael, but both seem very unlikely. The writers may have forgotten that little detail they mentioned back on season one.
On "The Fire" from season two, while a few of the employees were having a discussion about college, Dwight piped up that Michael never actually went to college. But just a few episodes later, on "Email Surveillance," Michael announced that he lived on Cup of Noodles, aka his "brain food," when he attended college. Maybe Michael made that lie up on a whim, or maybe Dwight didn't have the slightest clue about Michael's education (which is hard to believe since the Michael has always been Dwight's role model). Either way, we still don't know for sure who was telling the truth.
This continuity error is so easy to miss, but on "Tallahassee" from season eight, there's a scene where Dwight was playing a game of Taboo with Erin. While he was still holding the buzzer, with the speaker facing down, Jim smacked him. But in the following shot, Dwight's speaker was clearly face up. He obviously couldn't have flipped it over in such a short amount of time, and Jim's hit wasn't strong enough to move the object in his hand.
During that same episode, while a couple of staff members ventured out to Tallahassee with Dwight on a business trip, a few stayed behind at the office. Among those who went were Jim, Stanley, Erin, Cathy, and Ryan. And among those who stayed back was... Stanley. Though he was busy living his best life in another town, Stanley could also be heard yelling at Andy to answer the phone back at the office. Did he get cloned or something???
That emotional farewell between Pam and Michael was by far one of the most memorable scenes on the show, which is probably why most of us never took notice of this mistake. It was after Michael's security screening when Pam ran after him to say goodbye. She wasn't traveling that day, which meant she had no tickets and therefore, she shouldn't have had any access to the departure gates. Unless she actually bought herself a plane ticket to make it past airport security, it would've been impossible for her to freely go after Michael without being stopped.
Remember how Toby and Darryl tried to compete with each other to sell the most Girl Scout cookies for their daughters on season five? Well, there was one scene where Toby explained that this would be his daughter's first time selling cookies. But on an episode prior to this, he definitely mentioned his daughter selling Girl Scout cookies. Perhaps he lied on purpose to get more sales, but it's also likely that the writers forgot about his previous mention of it.
From day one, Angela has made it pretty clear that she's a vegetarian. However, on the episode "Jury Duty," Angela told Oscar: "The Senator and I wanted to wait, but we had just seen Thor, and there was way too much wine in my chicken piccata..." Then Oscar corrected her and said "Chicken Marsala." Of course, it's possible that Angela changed her diet and decided to start eating meat. But it just felt so sudden and a bit out of character.
Several moments before a giddy Dwight started singing "Ryan Started the Fire," the employees had to evacuate the office because of an incident. But right before they all exited, Dwight got all frantic and started throwing jugs of water into the smoky room to try and control it. His shirt got really wet as a result, but just moments later, it was like nothing happened because it was completely dry. How does this even make sense?
Remember when Toby climbed the parking lot fence after having that awkward moment with Pam on season four? The actor, Paul Lieberstein, originally wanted to do that stunt himself, but the showrunner and executive producer decided to use a stunt double instead. This explains why Toby was able to climb and jump over the fence with such ease, but if you looked closely at his face, you'd notice that it wasn't really him. Toby's stunt double was pretty much in plain sight.
We'll admit that the show did a great job of hiding most of the palm trees in California because they are almost everywhere. But of course, they could only avoid and hide so many. A close look at the background in certain scenes or at reflective surfaces would tell you that there were several palm trees there. For instance, in "Back from Vacation," palm trees were clearly visible from the office parking lot. In most cases, though, they were pretty easy to miss.
On the episode "The Alliance," which was only the fourth ep of season one, we got to see the staff newsletter. But if you looked closely, you may have noticed it has random sentences and a few made-up words. It actually says: "As anybody can easily tell, this newsletter doesn't really have a lot to say. It's really just a prop to fill some space and sort of look like a newsletter without really being much of a newsletter at all." It then went on to say that "at times we can probably get away with not using real English words, such as kjgowbiwiwpo, ovcviqvck, or the much beloved dfbiouvsulegphaelk."
Another small detail worth mentioning is that it's repetitive. The first paragraph says "Thanks to all of the staff and new contributing writers for putting this together..." But in the third paragraph, it says the exact same thing.
