Details Around The Office

During Holly's ethics seminar, Meredith reveals that for the past six years she had been sleeping with Bruce Myers, the Scranton representative for Hammermill, in exchange for discounts and Outback Steakhouse coupons. Staples had an exclusive hold on Hammermill products up until S3:E2, when Michael announced to Jan, Josh, Jim, and Dwight that he had, for the first time, gotten Hammermill to break their exclusive ties with Staples. Less than six years passed between S3:E2 and S5:E3, meaning Meredith could not have been receiving Hammermill discounts for the duration of her relationship with Myers.

Holly's real name is Hollis. While looking over Holly's shoulder, we can see a nameplate on her desk that reads Hollis "Holly" P. Flax. 

When Meredith, Dwight, and Mose break into Holly's car to leave a raccoon inside, Meredith inserts a crowbar of sorts between the door and the window to disable the lock. We can clearly see that the driver's side window had been open the whole time.
