Here's an idea. DeltAlum, you marry the ex Mrs. Jack Welch and then she becomes the future ex Mrs. DeltAlum. You get half of her half of JW's fortune which you share with the current Mrs. DeltAlum. How could she object?
I'll marry and then become the next future ex Mrs. Jack Welch. I'll get half of his fortune. Actually, he is way more than twice my age plus or minus seven or whatever formula James had. Does he have any single sons?
