Continuity mistake: At the end of the episode, we are shown a video of Dwight getting splashed with the milkshake from the point of view of the guys in the car. But it splashes differently the two times we see it. The first time it hits his lower body, and on the video, it hits him in his upper body.
Continuity mistake: Nellie and Pam are driving along, discussing what to make up about people's ancestry. Here, we see the same background go past Pam, a driveway with a black SUV on the right, and a white SUV on the left. This shot is only repeated in the angle where we can only see Pam, and the view out of the passenger side window. The car is driving along as normal, we see the two cars on the driveway, and then the car turns a corner, and we see the same shot all over again. (00:13:15)
Continuity mistake: In the episode's intro, as Dwight's aunt died, he explains the Schrute custom of inviting someone or not, by throwing red dirt or black soil at the person's face. In the first shot, Dwight shows the red dirt bucket by lifting his left hand, but when the camera angle changes to the side, you can see his right hand is lifted up with the other bucket. The camera returns to the front as he is still lowering his left arm, and then he proceeds to lift the black soil bucket with the right arm. (00:00:48)
Continuity mistake: They take a pledge to "We all drink them all" referring to the espresso flavors. Angela puts her hand on top of the pile and it flips between Oscar's hand and Stanley's hand under hers depending on the camera angle.
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.
