I was out walking with my 4 year old daughter. She picked up something off the ground and started to put it in her mouth. I took the item away from her and I asked her not to do that.
"Why?" my daughter asked.
"Because it's been laying outside, you don't know where it's been, it's dirty and probably has germs" I replied.

"Uh," I was thinking quickly, "All moms know this stuff. It's on the Mommy Test. You have to know it, or they don't let you be a Mommy." We walked along in silence for 2 or 3 minutes, but she was evidently pondering this new information.
"OH...I get it!" she beamed, "So if you don't pass the test you have to be the daddy."
