Gettysburg - S8-E8
Continuity mistake: While Andy continues the tour, Gabe stays behind to perform as Abraham Lincoln. Later on we see Gabe with the others, we even get a close up. A while later, when everyone is tired and sitting on the grass, Gabe doesn't seem to be there. Eventually the episode ends with Gabe finishing his performance.
Continuity mistake: Near the end of the episode when Robert California is escorting Erin out of the office, they are already in the parking lot speaking while it cuts to a shot of a concerned Andy in the conference room watching them from the window. A few moments later, Andy is shown saying goodbye to his girlfriend, while watching Robert and Erin leave the office. This should not be possible as they were shown to be in the parking lot already in a previous scene, with Andy watching as well. (00:18:38)
Continuity mistake: When Dwight goes to write the idea that Erin had of a coat check on the whiteboard, he begins to write cop, but in the next cut, the P is changed to an A for coat check. (00:09:40)
Tallahassee - S8-E15
Continuity mistake: Stanley can be heard as part of The Office yelling at Andy to pick up the phone, when he is supposed to be located in Tallahassee on the Business Trip. (00:05:30)
Tallahassee - S8-E15
Continuity mistake: When Dwight is holding the "Taboo" buzzer in front of Erin, he's holding it so the speaker is facing down. After Jim slaps him, he's holding the buzzer so the speaker is facing up.
Continuity mistake: Toby competes with Darryl to sell Girl Scout cookies. Toby says it's his daughter's first year selling them. However, earlier in the series, Toby agrees to sign Dwight's apology letter from corporate if he buys cookies from his daughter.
Continuity mistake: When the group is chanting, the first shot of the balloon has the forklift prong over it. In the next shot, Daryl is driving the forklift towards the balloon and the prong isn't over the balloon yet.
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.
