At about 04:14 minutes, Jed and Granny are discussing Thanksgiving in the Billiard room, but a quick shot of Jed's reaction to one of Granny's comments clearly shows kitchen cabinets behind Jed's head. Obviously making that quick reaction shot to take place in the kitchen, not the billiard room.
When Jed is talking to Elly and whittling the meat stabbers, the pile of shavings that collect on the table keeps disappearing as the shot switches back and forth.
The closing sequence was changed starting with this episode. Clearly visible on the right side of the screen is a crew member walking toward the camera and being yanked suddenly out of the picture. This happens again in the following episode before being discovered and cropped.
