Continuity mistake: When Jim is outside comforting Pam after she finds out her mother is dating Michael, he begins to explain a mallard recording device that Dwight gave to him and used a big hand motion that put his hand in the air. In the next shot, the hand that was in the air is now gripping his coffee cup.
Continuity mistake: After the banker asks Toby if there is any inappropriate behavior, a few seconds later there is a flash back of Season 3 Ep. 22 when it is the beach games and Michael is hosting a hot-dog eating contest. Michael says to Phyllis to "Dip it in the water so it'll slide down - your gullet more easily." In the flashback version, everyone says "That's what she said." In the real version, no one says anything. Not to mention Toby wasn't actually at the beach day, Michael told Toby to stay because "Someone needs to stay at the office."
