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)
Happy Hour - S6-E20
Continuity mistake: When Michael is doing press-ups Angela is sat, then she stands to see what's going on - away from her chair, it cuts to another shot, and she is sat down again.
Audio problem: When Ryan is saying "Angela drafted me", the audio is spliced after the word Angela and his exhaling is audibly cut off. (00:02:50)
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)
Other mistake: When Michael and Erin go back into Michael's office and start the video on Michael's computer, the "Play" button hasn't changed even though the video is playing. It should have changed to the pause button.
Continuity mistake: As Creed is catching the football, he drops a folder he had in hand into his lap. In the next shot, the folder is gone. (00:00:45)
Launch Party - S4-E3
Factual error: Michael and Jim are driving from their Scranton, Pennsylvania office to the company's headquarters in New York City for a website Launch Party. However, during the drive, it is clear by looking out the car windows at the mountainous and desert landscape that they are in California, where the show was largely filmed, and not in Pennsylvania, which does not remotely resemble that type of geography.
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.
Continuity mistake: When Michael begins the conversation with Jo, the door behind him is closed. After a few lines, the door is open. (00:19:10)
Launch Party - S4-E3
Continuity mistake: The way the numbers on the sales board are written by Andy change in between shots. (For example, the "305" is written differently, but still "305"; not that it becomes a "380" when Andy changes the number).
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.
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: When Jim and Michael are in the conference room with Jo, Michael messes up Jim's hair. A few shots of Jim later, his hair is nicely combed again.
Continuity mistake: When Angela is listening to Ben Franklin talk about flying his kite, her drink is near her lap, but in the next shot she's taking a sip from it.
Answer: In the 2007 episode "Ben Franklin" when Jim is talking to Pam there is a candy bar with a purple wrapper that says "Picar-" I assume picaroon, it's hard to see past Pam. I found this trying to investigate what that candy bar is lol.
