Character mistake: Meredith admits during the ethics seminar that she has been sleeping with Bruce, the HammerMill rep, for discounts on paper/paper supplies for the company, as well as Outback steak coupons, for 6 years. But, Dunder Mifflin did not begin selling Hammer Mill products until 3-2 "The Convention" when Michael got the contract.
Continuity mistake: In one episode Angela says she hasn't talked to her sister in years over an argument that she doesn't remember. When she's engaged to Andy and they're touring Dwight's farm he mentions she has multiple sisters. In the finale she only has one sister and apparently they are incredibly close.
Suggested correction: In the finale the "Sister" is Angela's best friend. Do you recall them each saying this is my older sister?
That's a common joke among siblings that are close, they're joking about which one is older. Rachel is Angela's sister, not just a friend. They even go on to say "we're very close. We even have our own special language", which is something common among siblings that are close. The mistake is valid.
Other mistake: Michael states that he and Jan have traded in their two cars for a Porsche (for her) however from earlier episodes we know that Michael's Sebring is a corporate lease.
Suggested correction: He's only saying it's a corporate lease to egg Dwight on cause he tricked him into thinking he got the manager position over Michael when Dwight tells Jan he could run the branch better in the waffle house, but right after screams "That's my car!" several times.
When he hit Meredith with his car he started it was a corporate lease again though.
Yes, he tells Ryan the accident occurred on company property, with company property so... Double Jeopardy they are fine. To which Ryan says, I don't think you understand how jeopardy works.
Take Your Daughter to Work Day - S2-E18
Continuity mistake: When we first see what Toby's daughter looks like it's in a photograph on his desk that Michael points out in 1-6 "Hot Girl". The girl in the photo has dark brown/black hair. The next time we see his daughter is in this episode, and she has bright blond hair. A completely different child actor was used. (00:07:35)
Suggested correction: The dark haired girl is Stanley's daughter and she goes to the Catholic girls school. If you look at Toby's desk on the wall is the picture of his daughter.
No, there is a picture on Toby's desk / on the wall of his desk, of his daughter in episode 6 season 1, where his daughter appears to have dark brown hair. Then when she comes in the office for "bring your kid to work day" she has blonde hair and blue eyes.
Suggested correction: Michael didn't establish the contract with Hammer-mill. Rather, he locked them up as an exclusive supplier. It's unknown if they were already selling the products to Dunder Mifflin alongside Staples and Office Max.
Wrong, Josh says they cannot sell Hammer-mill products as they are exclusive to Staples so therefore they wouldn't have been able to sell there products alongside as mentioned before until Michael made them an exclusive to them solely, Dunder Mifflin. Therefore the original mistake stands true.
