So I was bored yesterday and was wondering what to watch on Netflix. I hadn't seen any episodes of the X-Files in a while so I decided to watch that. I wasn't that aware of the series mythology so I just picked a random Monster-of-the-week episode, the one that seemed the most interesting. It was "Musings of a Cigarette-Smoking Man" and it was pretty saddening. After watching that, I felt inspired to make this thread, especially considering how many TV threads have reached the front page recently.
Tell me what you think is the most depressing TV episode of all time is. For me, it has to be the one I just mentioned. If you haven't already seen it, I recommend it.
