Kind of interesting how some shows, like Star Trek, utilize and display episode names prominently, to the point most fans refer to episodes by name rather than season and episode number; whereas other shows simply don't bother with them at all.
Fans of Twin Peaks have to just say "Episode 8" when they're referring to that episode. It was given a name after the fact for the blu-ray release, but posthumous episode names always feel more like "we needed to put some kind of text on the box/menus" rather than serious names, and since they're nowhere in the episodes at all, nobody uses them anyways.
