Continuity mistake: Michael and Dwight arrive at Wallace's house and discover that Michael is dressed like the servants, so they choose to exchange shirts. Behind the catering van, Michael removes his jacket and throws it on Dwight's shoulder, who grabs it and puts it between his legs. The frame switches from front to side, showing Michael removing his tie and hanging it on the van's mirror. When the frame goes back to front, Michael is shown still with his tie on, and throwing the jacket again, missing Dwight. (00:05:41)
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)
Other mistake: When Jim is editing the audiobook of Jo's autobiography, the waveform displayed on his computer program is inaccurate to the phonetics of the phrase being uttered. The crew of the show simply pasted in a random waveform of someone speaking a different sentence. There are a number of ways to tell it is inaccurate, but one is the periodicity of the waveform during the sibilant [s], which appear be noisy and not periodic. (00:15:20)
