No, I don't mean it in the sense of what would you think the very worst episode is. There have been enough threads dealing with that 
You lie in bed. Suddenly you wake up with a jolt and see Death standing at your bed. In his black robe, and long sickle, the complete works. And with DVD or Blueray copies of all Star Trek series.
He's telling you you are about to die. You will not be allowed any goodbyes to your family -death comes suddenly sometimes-, but you are allowed to (re-)watch one single episode of any Star Trek series before you go. No two- or more-parters or movies, so for example Best of Both Worlds as a complete story is out, though you are of course allowed to select part 1 or part 2 of that as a single episode. Also, there is to be no haggling about using the time for something else. It's either watching a single episode with Death and then leave with him, or leaving with him immediately.
So, which one will it be ? I'm not sure which one I'd pick myself, but I will tell as soon as I know. I might even be tempted to break my own rule and go with the Generations movie since that one very much deals with mortality and the purpose of life, (even though I do not consider it the best movie)....
