Most of these have been great.
I think Christopher's "Too Cerebral?"

is my hands-down favorite.
This episode is frequently listed as the worst episode ever. So I find it interesting that Shades of Grey came up here since Shades of Gray was Next Generations one and only clip show, and the worst of the series (maybe of all the various series). An episode that DID have a poetic title (And the Childred Shall Lead) gets my vote for the worst TOS episode. Any way, my entries (admittedly not as creative as previous entries) are....
I seem to be losing my mind.
