I noticed that early in season 8, in "The Money Machine", the old couch was replaced with a new one. But in "Out on a Limb," the old couch was back there. Were those shows possibly aired or produced out of order?

Looks like "Out on a Limb" was the first episode to be taped that season (taped on July 22, 1983, airdate was October 25, 1983), and "The Money Machine" was taped afterward, on August 19 but aired on October 18, a week before "Out on a Limb." So that was probably why.

The same mistake was made with the curtains in Season 3. In "Chrissy's New Boss" we see Mr. Roper installing new curtains, but in the episode right before that "Larry's Bride" the new curtains are already in place (same reason---"Larry's Bride" was taped after "Chrissy's New Boss"). I guess the set decorator/continuity guy was sleeping on the job. :lol:
