Lonesome Dove
written by Larry McMurtry

Carrie decides that the basement, where Arthur's sleeps, is too cold for him to stay during a cold snap. She sets up a temporary room for him upstairs in the office to ride out the cold spell. The below-freezing temperatures last longer than they expect, and having Arthur right across the hall is more than they bargained for. When the weather finally begins to warm up, they hope that Arthur will return to his room in the basement so they can have the upstairs back to themselves again. However, it seems that Arthur has gotten quite comfortable with the new set up and has no intentions of going back to the basement.

In this episode, the whole Office participates in a company-wide weight loss contest. Pam goes to New York City for art school, causing her and Jim to have to adjust to being temporarily apart. Also, awkward tension is created between Michael and Holly after she accepts a date with another man, and Angela and Dwight continue their secret relationship, Angela's upcoming marriage to Andy notwithstanding. The episode was voted the second best episode of the season in a poll at the fan site OfficeTally.
