Came across this item online this afternoon.
"Louisiana Town Ditches 666 Area Code Over Religious Concerns"
"What happens when you combine a strongly religious community in the south and the unfortunate telephone area code of 666? Hilarity ensues, of course! Ok, maybe not too much hilarity, but some."
I had to chuckle about it, of course. I would ALMOST be willing to pay to have that area code. I certainly wouldn't want to get rid of it if it were assigned.
Anyway, according to Heinlein the number "666" is a mistranslation. The actual number is 6^6^6 (6 to the sixth power to the sixth power, or 6 raised to the 46656th power - a truly phenomenal number) and represents the number of possible universes. (The Number of the Beast by Robert Heinlein.)
