“ I've never seen or touched anything.Can you explain then how you had children?You're right. It's true I have four kids. Four! But still I have never seen the male organ. He came into the bedroom, he turned off the light, and then Bam! Bam! Bam! and voila I was pregnant! What's more, I was granted four girls. So I have never seen penises. ”
