I suspect you're upset at Atticus not me, but since I was in the line of fire I feel some response is in order.
Although revealing that BF makes an appearance in Spanish Fry is technically a "spoiler" in that it communicates information you would not know except by watching the episode, I can't see how, in this particular case, it would damage your viewing enjoyment once you finally get to see it. This is sci-fi, anything is likely to turn up now and then. Why would BF be such a surprise? Yes, Atticus should have hidden it, but he didn't do much damage. Oh oh, by saying that, I have communicated even more information. Now I'm guilty too!
That said, it's good standard practice to hide spoilers. Atticus, if you use the "Reply" link instead of quick-post, you get an enhanced posting window with a palette of smilies etc to the right. One of those is "spoiler". I will here attempt to use it for my first time:
Put in here, all the neato 4ACV stuff that those poor folks in Sweden won't get to see for N years.
There, that was easy. Hard to remember to do it, though.
