Nah, tie between Best of Both Worlds part 1 & 2 and Decent part 1 & 2- Awesome episodes.

mmmmm, Bebe.

Sorry, I hated this episode, along with the "Data dreams that Troi is a cake being carved up" and many other absurd "everyone gets possessed" shows of the last 2 seasons. But I did like "Cause and Effect".

A first season episode, that was never explored further and should have been - Conspiracy. Parasites are taking over the Federation. Picard and Riker save the day at the end, but a message was sent out before the baddy was killed at the end. It could have set up a quite a big story arc, but what happened was never further pursued.

I remember the first time I saw "Cause and Effect". It was such a big deal to me to see the Enterprise get blown up 5 times. But nobody seemed to understand because I didn't know anybody that watched TNG at the time.

Yesterday's Enterprise

The Inner Light (stardate 45944.1, airdate 30 May 92).
By far my favorite episode.

I actually thought Genesis was a little silly. I mean everyone devolving. Really. I thought maybe all of the humans should have just turned into apes.

Ups, too late.

Bebe Neuwirth was in an episode. I don't know the title, but it's the one where Riker is undercover on a planet which is under investigation (the society is not so far developed that it can be contacted by the federation yet). He suffers near fatal insuries, and the rescue mission brings on all kinds of diplomatic problems and discussions about when to contact a new civilization.
