"Mama," my eight-year-old son said. "The heart has a butt that never stops working."
I looked at that kid. "Bubba, the heart does not have a butt."
"Yes, it does," he said. "It pumps poop and pee out the back end into the body."
I shook my head. "No, Bubba. Here's how it works: Blood from the lungs goes into the left atrium, through the left ventricle, and out into the body. Then it comes back through the right atrium and right ventricle and returns to the lungs to get more oxygen. It has absolutely nothing to do with bodily excrements!"
My son looked at me like I had rocks in my head. "Mama, you don't know what you're talking about. The heart has a butt. My teacher said so!"
Alright, then. I see I'm going to have to pay a little visit to that institution called a school to find out what kind of anatomical nonsense is being spewed to our kids!
