Sigh..
Let's go back and look at what I wrote:

>>So... in Genesis 1:3 "Let there be light...." means "let's all shed some extra pounds?"

PS-
You'll be pleased to know that after having broken my toe in a silly fall last week I went to my toenail clipper and was happy to learn that he can actually do things that MD's are expected to do.
Actually, he did a wonderful job and I'll stop haranguing him about toenail clipping.
