"Daddy, does Mommy have a penis?" the little boy asked with no signs of shame.
"No, son, she doesn't have one," Dad responded, trying to be serious.
"Then how does she pee?" the little boy continued.
"Well let's just say that your Mom has a different peeing system," he said, laughing.
"That doesn't seem right at all. Do you have the same peeing system like her, Dad?"
"So Dad, you do have a penis?"
Dad looked down at his crotch and said:
"No, your mother killed that little thing years ago!"
