Wanna gross your kids out?
Ask your kids the following:
Incest (marrying your sister) and polygamy (marrying more than one person).....one was OK and is no longer, the other has always been wrong....which is it?
They almost always say polygamy was OK at one time. When you explain the math of getting a world populated you will thoroughly enjoy their face when they think about marrying their sister or brother.
