Because They Were Clean

I would have to say "Duet" (1x19) was the best episode of season one, and definitely one of the best episodes of the series.

According to the Companion Guide, this was what they referred to as a "bottle show", or a show produced with a low budget because they had already spent a lot of money for the season. There aren't a lot of special effects in this episode, but there is a lot of talk.

This scene gives me chills, but not so much when taken out of context like this. In the episode, a Cardassian is trying to make his people acknowledge their guilt over the occupation of Bajor by pretending to be the butcher of Gallitep, getting caught, bragging about everything that went on there, and then put on what would be a very public trial.

The episode did have its bad parts, though. A terrible actor playing a drunk Bajoran has a few lines, "Am I still drunk? Or am I in jail with a Cardassian?" Blah. But there is plenty of great exchange between Kira and Marritza that the bad parts hide in the shadows.

Death to the Opposition

This little clip, from "Take me Out to the Holosuite" (7x04), involves the crew of DS9 getting in to a baseball match against a crew of all Vulcans whose captain happens to be an old rival of Sisko's since the academy days. Since Sisko's specialty is baseball (and smashin' through Dominion ships), he's confident he can beat the Vulcans. At the start of the game, Sisko says, "All right, Niners, let's hear some chatter!" Worf's response is classic:

He loosens up a bit (for Worf) and lets the chatter fly: "Death to the opposition." Hahaha. OK, so non-Trekkie's may not laugh, but any Trekkie or Niner that knows Worf will.
