How about Abraham who supposedly started all this crap, was he married to one woman? Oh wait, NO! He had three. Also of note, his main b*tch was also his half sister! Then there were the others, and how about his RIGHTEOUS descendant Lott, he didn't even have the decency to marry his two daughters, just bang them.
