I don't know if this was brought up when TLG premiered... I don't think so, so I'll go ahead with it anyway.
The other day I turned on the Sci-Fi channel, and there was a cheesy 80's vampire movie called "The Lost Boys." Perhaps the Daria episode's title was an obscure reference to this film, comparing Val, corporate magazine owner that she is, to a bloodsucking vampiress? If you haven't seen the film and want a relatively good plot synopsis, you can read Roger Ebert's review of it here: http://www.suntimes.com/ebert/ebert_reviews/1987/07/245550.html Comments, anyone?
Anyway... I liked the movie, BTW, if only for it's cheesiness. Oh, and of course the groovy 80's soundtrack!
