How many great-grandmothers is too many to be President?

Maybe there is a clinic somewhere where Republican Presidential hopeful Milt Romney can get cured of the polygamous habits of his not too distant ancestors. If not it could prove somewhat of a problem for the former Massachusetts Governor who seems to have more that legally permitted number of great-grandmas as one of his great-grandfathers had at least five wives simultaneously.

It must make Xmas shopping that extra bit more difficult.
