To hide a mess Eddie made, his girlfriend, Wendi, tries to distract Peggy by insisting she take a day off with a fun day out while they take care of the housework. To everyone's surprise, Peggy accepts the offer and requests Wendi tag along, with the ulterior motive of teaching her a lesson. Meanwhile, Eddie enlists the help of his brothers to clean up and keep Mike out of the house while Wendi and Peggy are out. Elsewhere, Pat introduces Timmy to his secret dog.
In a working-class neighborhood outside Los Angeles, Mike and Peggy raise eight boisterous boys during the 1970s. There are 10 people, three bedrooms, one bathroom and everyone in it for themselves.
