In the episode Crock Tales (which is the episode right before the series finale) there are flashback clips shown. I am wondering if all of the clips are from previous episodes. I don't recall seeing all the clips in previous episodes.

Well the one's in that episode were not, thankfully. I hate waiting a whole week for an episode, only to find I have seen it all before.

None of the clips are from previous episodes I think. I noticed that when they went back in time that Daphne and Roz's hair was jet black. Neither's hair was that color before. I chuckled when I saw that.
