Continuity mistake: Michael's scarf is above his collar in the first shot, but moments later, seemingly without moving, his scarf is tucked below his collar. (00:06:40)

The Office (2005)
1 continuity mistake in The Duel - chronological order
Starring: Steve Carell, John Krasinski, Rainn Wilson, Jenna Fischer, Leslie David Baker
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.
Michael Scott: This is an environment of welcoming, and you should just get the hell outta here.
Trivia: Michael says his favorite "Glee" character is "the invalid", referring to Artie Abrams. Artie is played by Kevin McHale. McHale appeared in one episode of "The Office", s04e03 (Launch Party), as the pizza delivery boy that Michael ends up "kidnapping."





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.
