I remember a story on CD ROM from back in the day. Don't think I ever got it to work right, but the title of it was "Soft Kill" and it was a story about how Japan decided to get some payback for WWII and launched a massive cyber attack...the US was crippled (in the story).

As far as pretty girls asking about the definition of infrastructure...I might have said, "It has to do with things like where the utilities run...why don't you come over to my tent and I'll show you my maps..."
