Season 5: Episode 102: Window Pain
Mike and Debi, a bright young couple, move in next door to Doug and Carrie. The Heffernans don't make the greatest first impression as an argument they're having can be heard throughout the neighborhood. Carrie feels that her job, as a legal secretary, and Doug's, as a truck driver, are insignificant next to her neighbors, who both hold professional jobs. She tries desperately to make a good impression on her new neighbors by inviting them over for dinner, but Doug thwarts her plan. Meanwhile, Arthur takes advantage of Spence's job at the subway by insisting on free rides.
