Final answer:
In the episode 'Branch Wars' from 'The Office,' Pam, Oscar, and Toby form the 'Finer Things Club,' which focuses on the discussion of literature and culture in a sophisticated setting.
Step-by-step explanation:
The exclusive club that Pam, Oscar, and Toby establish in the The Office episode "Branch Wars" is called the Finer Things Club. This club is devoted to discussing books, art, and culture while enjoying a sophisticated atmosphere away from the daily office grind.
The members take turns to choose a book or cultural subject to discuss, and everyone in the club is expected to contribute to the discussion in a thoughtful manner.
The Finer Things Club is known for its exclusivity and the fact that other characters in the show, such as Jim and Andy, express an interest in joining but are not permitted or struggle to fit in with the club's culture.
