“My daughters’ birth certificates were 10637 and 10638, and Obama’s was 10641, so his mother must have come in after I did,”
I would have thought that the order of the births would have determined the numbering on the birth certificates. Basing the numbers on the order in which the mothers entered the hospital doesn't make any sense at all.
It could make sense. See #98 for a plausible scenario. I'm not saying it's what happened, but it could have.
