After Bill and Judy catch Brian, Lauren and their friends drinking in the basement, they decide to set an example and abstain from drinking for an entire month. Unfortunately, Bill and Judy's infamously wild Super Bowl party takes place during that time. Brian and Lauren are impressed that their parents have gone alcohol-free for a solid three weeks. However, when Super Bowl Sunday dawns, the "holiday" may be too much for Bill and Judy to handle sober.

The guys down at the toilet store get a new boss "a young, brash, Harvard graduate" who develops a friendship with Brian. Bill shamelessly benefits from the situation until Judy steps in and leaves no question that she's still the boss. Meanwhile, Tina and her mysterious new friend frustrate Lauren.

Brian has returned from his summer abroad and he should be excited about starting his senior year of high school, but he left his heart in Italy and can't stop thinking about the girl he met. Meanwhile, Linda's so desperate to keep Perry from a long-term gig on the road that she resorts to injuring him.
