Burt and Virginia try to help a couple they heard arguing on Hope's baby monitor.

Virginia encourages the family to submit their own inventions in the National Invention Convention Extravaganza, so they could win the cash prize. Burt and Andrew team up to create unusual flavored yogurt, while Sabrina and Jimmy create a new baby mop.

Jimmy and Sabrina continue building their relationship by learning more about their strange habits and childhood fears. Meanwhile, Virginia learns more about a habit Burt has been hiding from her for years.

Following the revelations of the "Inside Probe" expose of their family history, the Chances are put on trial in a fight to retain custody of Hope.

It's a "My Name is Earl" reunion as the Chances throw a birthday party for Hope. Jason Lee reprises his guest-star role as former rock star Smokey Floyd, and he is joined by guest stars Jaime Pressly, Ethan Suplee, Nadine Velazquez and Eddie Steeples as Natesville locals who all band together to save the party.
