Brian, Lauren and their friends are caught sneaking beers, so to set a good example, Bill and Judy join other parents who've vowed not to drink alcohol for a month.

Louise announces she's getting hitched to her new boyfriend and, to Judy's chagrin, would like her daughter-in-law to perform the maid-of-honor duties, all of which need to be completed in just two weeks. Meanwhile, Bill is thrilled that his mother is getting married, mostly because it means she'll be spending less time with him and his family. Too bad Bill's father has to show up and threaten to spoil everything.
