Goofs, Gaffes, and Inconsistencies in "The Office" (US): Or Things You Notice When You Watch Every Episode, Back to Back
Season 1, Episode 4: "The Alliance" and Season 5, Episode 3: "Business Ethics"
Jim signs Meredith's card with a joke suggesting she fudge her age because she's an accountant. Not only does she not sit with the other three accountants, it is later revealed (Season 5, Episode 3: "Business Ethics") that she works in supplier relations, not accounting.
Season 2, Episode 2: "Sexual Harassment" and Season 6, Episode 5: "Niagara: Part 2"
Shannon Cochran plays Pam's mother in Season 2, Episode 2, while Linda Purl played her mother in subsequent episodes, starting in Season 6. According to Wikipedia, Cochran was unable to return to play Pam's mom for the wedding episode (Season 6, Episode 5: "Niagara: Part 2"), due to scheduling conflicts (a year-long theater contract).
Season 2, Episode 12: "The Injury" and Season 5, Episode 17: "Lecture Circuit: Part 2"
Throughout the show, Meredith only ever acknowledges one child (Jake or Jakey, who later sports a face tattoo and dances at Angela's bachelorette party).
In Season 5, though, she mentions having a second child for the vacation, yet we never hear about this child or see him or her.
Season 2, Episode 13: "The Secret" and Season 4, Episode 3: "Launch Party"
Who came first, Jim or Pam? (That's what she said...?)
According to Episode 13 of Season 2, Pam started after Jim. Flash forward to Season 4, Episode 3, and we hear that Jim started after Pam. I'm so confused.
Final Verdict: Episode 12 of Season 6 ("Scott's Tots") confirms that Jim started after Pam. When determining the results of Employee of the Month, we learn that Jim is employee number nine, while Pam is employee number three.
Season 3, Episode 10: "A Benihana Christmas"
Michael and Andy pick up a couple of Benihana waitresses after Michael's realtor breaks his heart. Cindy, Michael's date, looks noticeably different upon arrival at the office. Even Michael gets confused and scribbles on "Cindy's" arm with a marker to identify her. IMDB identifies Cindy #2 (on the right) as "Nikki", though no one by that name is ever referenced in the episode. Oops.
Season 4, Episode 13: "Job Fair" and Season 6, Episode 26: "Whistleblower"
Pam speaks to someone at a booth about a job in graphic design - turns out it's Nick the IT guy (see Episode 16: "Manager and the Salesman" and Episode 26: "Whistleblower" of Season 6). Graphic design and IT aren't completely unrelated: graphic design is often done on a computer and IT professionals also work with and on computers (*cough* reaching *cough*).
Fun Fact: Angela Kinsey, aka Angela Noelle Martin, was pregnant during much of the fourth season. She sports a noticeably fuller face starting in Episode 13 ("Dinner Party") and spends much of the season with her tummy out of view.
Season 4, Episode 14: "Goodbye Toby"
At the end of the day, Toby's watch (formerly Michael's) goes off. He says "Oh, some kind of...alarm." If you recall, Michael set the watch earlier in the day to go off at the end of the day (presumably at 5pm), indicating the end of Toby's last day. However, when Michael gave Toby the watch, Toby immediately set it to Costa Rica time (two hours behind local Scranton, PA time).
Season 5, Episode 7: "Customer Survey"
Dwight shows Andy and Angela some Schrute Farms promotional materials. The gentleman representing a funeral home from the career fair (Season 4, Episode 13: "Job Fair") appears in the brochure. He's flanked by a much younger bride in the photo.
Season 6, Episode 11: "Shareholder Meeting"
In the montage of Recyclops' (excellently portrayed by Dwight) history, the order of receptionists is incorrect: in reality, Ronni (played by Dale Raoul on the right) replaced Pam when she moved to New York for design school, then Ryan replaces Ronni after he is ousted from Dunder Mifflin for fraud. In the flashback, however, Ryan precedes Ronni as the receptionist.
(More) Office Trivia
Dunder Mifflin had an unusually high number of green-eyed employees. Six of the twenty (30%) main employees had green eyes (Jim, Michael, Angela, Pam, Nellie, and Pete), while only about 2% of the world's population is green-eyed!
Similarly, approximately 2% of the world's population has red hair; however, three out of twenty (15%) Dunder Mifflinites are red heads: Erin, Nellie, and Meredith!
Season 6, Episode 22: "Secretary's Day"
During a confessional, Andy says the following: "If it wasn't for secretaries, I wouldn't have a stepmom."
However, in later episodes, Andy's parents are still married (see Episode 4 of Season 8: "Garden Party").
In Season 9, though, Andy's father abandons the family and runs off with another woman (Episode 6, Season 9: "The Boat").
Bonus Gaffe: Season 4, Episode 14: "Goodbye, Toby" and Season 8, Episode 4: "Garden Party"
Introducing Andy's parents: Andrew and Ellen Bernard
Wait - didn't Andy say that he was named after his father Walter until he was about six (see Season 6, Episode 17: "Delivery: Part 1"), when they renamed him Andrew and gave the name Walter to his younger brother (portrayed by Josh Groban)? Ouch.
Re-Introducing Andy's parents: Walter and Ellen Bernard!
Season 7, Episode 2 "Counseling" and Season 6, Episode 26: "Whistleblower"
Dwight introduces Pam and Jim to the "Sesame Avenue Daycare Center", but in a previous episode (Season 6, Episode 26: "Whistleblower"), it is revealed that the building is located at 1725 Slough Avenue. (Context: Dwight is speaking to his realtor on the phone and instructs him to make an offer on the building where Dunder Mifflin is located.)
Season 7, Episode 7: "Christening" and Season 7, Episode 8: "Viewing Party"
Admittedly this is super nitpicky, but the infant playing Cece (Pam and Jim's first baby) is noticeably not the same as the infant in the previous episode ("Christening"). Though neither baby is credited on IMDB.com, the naked eye reveals that they are in fact different actors.
Season 7, Episode 9: "WUPHF.com" and Season 9, Episode 17: "The Farm"
Blink and you might miss Blake Garrett Rosenthal's appearance as a random "Hay Place" patron in Season 7's "WUPHF.com". Don't worry, you can see him again playing Dwight's nephew in Season 9's episode, "The Farm". Awkward.
Season 7, Episode 22: "Goodbye, Michael"
SPOILER ALERT: Michael leaves Dunder Mifflin.
Now that we've gotten that out of the way, we can resume our hypercritical examination of The Office. In Michael's farewell episode, Pam is uncharacteristically out of the office when Michael is saying his goodbyes. Miraculously, she catches up to him at the airport after he's gone through security, resulting in a touching goodbye scene. Miraculous because Pam manages to get through security (note that her shoes are off when she catches up to Michael) without a ticket - unheard of in our post-9/11 world.
Season 7, Episode 24: "Dwight K. Schrute, (Acting) Manager" and Season 9, Episode 11: "Suit Warehouse"
As acting manager in Season 7, Dwight accidentally shoots a gun, leaving a hole in the carpet. Upon examination of the hole, Oscar discovers hardwood floor beneath Dunder Mifflin's hideous textile floor covering.
You'd think he would've remembered this, but in Season 9, he rediscovers it after the office binges on espresso from the new machine. From Wikipedia:
"As the rush dies down, they all begin to sweat profusely...and begin to frantically tear up the carpet of the office to reveal the hardwood underneath and try to relocate the copy machine to another position at the same time."
Season 8, Episode 24: "Free Family Portrait Studio" and Season 2, Episode 18: "Take Your Daughter to Work Day"
Jazz Raycole plays Stanley's daughter in the "Take Your Daughter to Work Day" episode. Years later, she's portrayed by a clearly different (and uncredited) actor. Sure, Melissa (Stanley's daughter) has aged, but unless she underwent an Extreme Makeover, it is unreasonable to try to convince us she's the same person.
(Interestingly, Jazz Raycole was replaced on another sitcom, My Wife and Kids, after one season. Jazz, you've got some 'splainin to do!)
