Sundays are usually reserved for Jessica and Evan's weekly Costco run, but Jessica is thrown for a loop when Evan decides to go to church instead. Meanwhile, Marvin treats Louis to a free teeth-whitening session, and Eddie and Emery find creative ways to get rid of the healthy cereal in the multi-pack.

While the Huangs are out at the movies, Evan is accidentally left home alone, and Jessica vows to make it up to him. Meanwhile, Marvin takes a spill and is visited by Ghosts of Christmas Past, Present and Future.
