In Other Words prompt and my response.
I think Mr. Berle is onto something.
It seems to me that when a woman gets pregnant
along with a baby growing there should be
an extra arm and hand that sprouts at the waist.
It would be fully grown and operational
when the baby is born.
When the child goes to first grade it
would drop off and disappear.
I thinkk this sounds quite reasonable.
There is the added plus that once the third arm falls off
the mother gets a new wardrobe because she
no longer needs clothes with an extra arm hole.
