Character mistake: Meredith admits during the ethics seminar that she has been sleeping with Bruce, the HammerMill rep, for discounts on paper/paper supplies for the company, as well as Outback steak coupons, for 6 years. But, Dunder Mifflin did not begin selling Hammer Mill products until 3-2 "The Convention" when Michael got the contract.
Character mistake: Erin is shown drinking an espresso in 5-25 "Café Disco". Later in the series in this episode, when Clark brings an espresso machine in that was given to him by Jan, everyone decides to try every flavor. In an interview Erin starts rambling but then remember the actual question she was asked, have you ever had an espresso before, she said she had not.
Character mistake: When Dwight and Toby drive by Darryl's house to investigate his injury, a New York Yankees sign is on the front porch of Darryl's home. Throughout the show, however, it is strongly implied that Darryl is a Philadelphia Phillies fan. This is a character contradiction. (00:10:19)
