S3, E2: After two more in a series of disagreements with neighbors Hal and Maggie, Paul tells Jamie of a rumor about their building going co-op. When Hal and Maggie unexpectedly drop in to apologize, Paul suspects something is behind their sudden friendliness, while Jamie suggests joining them to walk their dogs and take in a movie. However, only after calling to charge the movie tickets to a credit card do the Buchmans discover that Maggie and Hal want to buy their apartment. Meanwhile, in spite of their owners, Murray falls for Hal and Maggie's purebred show dog, Sophie. Refusing their neighbor's generous offer for their apartment, Paul and Jamie head for the movie after inviting Ira and a date to meet them. However, when his mother arrives with Ira and learns of the coop rumor, she suggests that Paul and Jamie consider moving to her building. After pondering the idea of leaving the city for a quieter life in the suburbs, Paul learns that Murray is going to be a father. But, even though the apartment is bigger, nicer and cooler then their own, Paul and Jamie agree to ignore Sylvia's hints about moving while doing their best to keep Murray and Sophie apart. After another uncomfortable encounter in the hallway, Jamie suggests paying half of Sophie's veterinarian bill and Hal curtly accepts, but refuses to warm up to the Buchmans. However, when Sophie decides to have her puppies atop Paul's favorite sweater, the warring neighbors join together and call the building's super to assist in the delivery. Finally, after the puppies arrive, Paul and Jamie decide to stay and settle back into their conflict with Maggie and Hal.
