Jake: 7 yr. old son
Me: Mom, 30 something
Jake: Mom, I've got a question for you. Why do girls have babies and boys don't?
Mom: (thinking wtf is your father?) Well, you know how inside your belly you have your lungs and heart and liver?
Mom: Well, girls have an organ that boys don't have and that is called a uterus. This is where babies grow inside the mommy's belly and since boys don't have a uterus, you can't grow a baby. (Unless you are the guy that used to be a girl and didn't make the total change to a guy and still had his uterus.....but I didn't go into that detail!!)
Jake: Ohhh. So then they grow up, get married and then start growing babies?
Mommy: ummm, yep, that's what happens.
