Robert Kopp tells about the woman who was walking with her young daughter. The little girl picked up something from the ground and started to put it in her mouth, but the mother told her to throw it away because it was dirty with germs.
"Mommy, how do you know so much?" the girl asked.
"Well, it's on the mommy test," her mother replied. "You have to know all about such things or you don't get to be a mommy."
The daughter thought about it a moment, then replied, "OK, I get it. So if you flunk the test you have to be a daddy."
