Interesting question. I pondered this a moment and was actually surprised at the first thing that popped into my head. My answer. .
I could watch the Voyager episode with Andy Dick in it over and over and almost never tire of it. It's probably the ONLY VOY episode I actually sat through from beginning to end when it first aired. Actually, come to think of it, I could probably also say the same of the other VOY episode that centered on the holographic doctor. But I'd sooner watch a reality show about people eating raw sewage than sit through anything else VOY ever again.
Not that the series sucked or anything. Just saying.
I also rather enjoyed Stargate SG-1's 200th episode.
