Lydia becomes jealous when the kids befriend Crystal, then makes them go with her to visit their former housekeeper.

Ben, Oliver and Regina throw a wild New Year's Eve party so they can meet hot dates, but their plans are quickly thwarted by the arrival of their parents. Lydia has invited a handsome man she met at the hospital to the party and has no idea that he is Crystal's father.

The whole family gets stuck together in a snowy mountain cabin and the guys find a pregnancy test, but they don't know if it belongs to Crystal or Oliver's new girlfriend (who has slept with Oliver and Ben).
