Mo' Chinese Mo' Problems - S5-E5
Continuity mistake: At one point you can see Marvin's red Jaguar parked in the driveway. He sold this car in the first episode of this season.
Continuity mistake: Grandma and Emery are sitting at the dinner table. The money box is closed, cut to Emery and it's open, cut back to Grandma, it's closed, and she opens it to give him money.
Continuity mistake: While Jessica and Louis plan their upcoming week at the dining room table, Jessica's hand (and the pen held in it) change positions as the camera angles change.
