How do they really know how many babies are out there? They don't. They only have the reported numbers. So many babies are born in the jungle, safari, on the Nile river, in the streets (sad), etc.
666...not a comfortable number for me. If the cash register rang $6.66 (that's happened a few times), I always paid an extra penny. $6.67. Whew. One time a friend ordered 6 Route 66 drinks from Sonic...I was like, "Um, can we please order one more?" He said, "Why? There are only six of us!" I had to think a minute..."Oh! I'm pregnant, so really there's seven of us!" I didn't want to admit that I hated the number.
