Will & Grace & Vince & Nadine - S7-E7
Continuity mistake: When Jack retrieves the dinner plate of food from the oven, when he brings it back to the table and sits next to Will, he puts the plate down and it have a foil covering on it. But in the next shot he begins to eat from the plate, with the foil instantly off (sitting on the table) and Jack having not removed it. (00:12:10)
