A woman was out walking with her 4 year old daughter. The little girl picked up something off the ground and started to put it in her mouth. The mom took the item away from her and asked her not to do that.
"Why?" the daughter asked.
"Because it's been on the ground, you don't know where it's been, it's dirty, and probably has germs," the mom replied.
At this point, the daughter looked at her with total admiration and asked, "Momma, how do you know all this stuff, you are so smart."
The mom was thinking quickly. "All moms know this stuff. It's on the Mom Test. You have to know it or they don't let you be a mom."
They walked along in silence for 2 or 3 minutes, but the girl 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 dad."
''Exactly," the mom replied back with a big smile on her face.
