I have a sticker on my car that says, "There is no place like 127.0.0.1"
I get to explain it to a lot of people, and I'm usually rewarded with a blank look, followed by a pitying look, followed by parents holding on tightly to their children as they move away slowly at first, then quickly, never turning their backs on me.
Such is the life of a geek among normals.
There will be 10 kinds of people in the world: those who get this shirt, and those who don't.
(Okay, that was taking it just a little to far, I will admit.)
