I'm watching the Swedish silent film "Gösta Berlings saga"
, and there's a wealthy Swedish residence in it called 'The Borg Estate'.
This immediately reminded me of the "Star Trek: First Contact"
line, and I decided to look up "Borg" to find out if it really is a Swedish word and Lily was actually right (despite her line clearly being written for humour).
This thread was the first thing that came up in a Google search. The only references I can find to "Borg" as a Swedish word are the aforementioned tennis player and this movie.
I doubt Moore and Braga were thinking of the movie when they wrote the line (unless they're Greta Garbo fans, since it was the '30s star's film debut in a starring role), but I think this is a fun bit of trivia and reference to the movie anyway, whether it was intentional or not.
