Season 3: Episode 72: Swim Neighbors

Doug and Carrie meet the neighbors after a hurricane destroys both of their backyards. Carrie breaks their hearts by telling the truth and rejects the idea of a combined backyard. So the neighbors retaliate by disrupting their privacy by making an aboveground pool in a small space. But as Carrie tries to mount a lawsuit, Doug can't deny the temptation and joins the other side. But before the pool goes down, Carrie takes a quick swim and later, Doug tries to enjoy the lawn sprinkler.
