You're right. I didn't make that connection. They use that number so it won't match a person's home phone number and 555 is the numbers used when dialing for information. At least that is how it was when I was a kid.
The 666 is associated with the book of revelations and Satan. There goes that apocolyptic theme again!

I think it may be geopolitical in nature too. Afterall, Tony Blair is in it.
So I have 555 (information) and 666 (revelations? the devil?) The numbers were on a green bible. I peel them off and that crazy woman chases me with a weapon. I described it as an oval on a handle. It could represent feminine vs. masculine, or the Ankh. Then Tony Blair promises sex every day.
Strange. I'll have to think about it some more.
