The premiere episode of the 2nd season and the debut of the striped wallpaper that would align the living room set for the remainder of the series.
In this season 2 opener, there are a few notable set changes at Ray and Debra's. The front door and coat rack are no longer directly at the bottom of the stairs. Instead, there's a new window. The front door is now to the right of the new window and the coat rack has moved to the right of the door. A table and lamp (previously underneath another window) have moved to underneath the new window. The wallpaper has changed color and pattern (from diamond-shaped to stripes), and there's a new drop-leaf coffee table.
In the opening scene of the front exterior shot of Ray and Debra's house, there's a newly planted tree in the front yard next to the street (not present in Season 1).
