"Shades of Grey", which I enjoyed all right despite its status as a 'clip' show. Right before that I saw "Peak Performance" for the first time. I don't know why Picard thought Worf would try the same trick twice in a row...
Agreed about Shades of Grey. It's not one of my favorite episodes, but I do enjoy seeing some of the clips from season one and two (both of which I enjoyed, despite most fans disliking them). It's kind of like looking through a photo album at old memories, it's very nostalgic.
