In the season finale, the office has an attractive visitor; and Jim, Dwight, and Michael all try their hand at impressing her, Pam and Roy's dysfunctional relationship is on full display, and Michael may have addiction to the Filet o Fish. 

Episode note: a quick IMDB search reveals that Kathy Bates is the only other Office cameo to win an Academy Award. Neither Idris Elba nor Jim Carey have won an Oscar - or even been nominated - though both have won at least one Golden Globe.
