I've noticed for a while now that on KOQ, they recycle the old N&S sets.

Tonight I was watching the episode where Arthur dates Doug's Aunt Sheila.
In the final scene, Arthur and Doug are standing in the hallway where Ned's apartment was, but it's redesigned in red with white boarders. (this actually made me feel all warm and fuzzy because Ned lived there and then Doug and Arthur were there!)


In another episode, the Amanda's Amuffins set has been redesigned and I noticed it because Carrie and Doug sit on the indoor steps of the enterance

Carrie's office uses several of the wall pannels from Ned's workplace, Kirkland and Haywood, unchanged.
