Bee, Andy, and Roger finish dinner and rise from the table, Roger follows Bee into kitchen. Upon his return all the decor has changed, for example: The knic-knacs on the china cabinet are different and the largest plate is gone,the cabinet is different, the wall has shrunk, the molding has changed, curtains too, a table shows up, etc.,. But as you look closer it is obvious that it was not two different sets, IT WAS THREE! There are 3 types of molding, 2 different pictures on the wall plus one wall with no pictures. When Roger is seen alone in the camera frame the back-ground is different than when all 3 or 4 people are in the frame, and both back-grounds differ from the one seen at the very end of dinner when they all rise (this of course is the start of the time line). It's the darndest thing.
