Summary of reproductive biology, as conveyed by my four year old neighbor:

1. "I was in my mommy's belly"
2. "You was in your mommy's belly."
3. "Everything was in mommy's belly."
4. "Except fish. They don't do it."
5. "Then you crawl, crawl crawl down to, um, butt? Come out!"
6. "That cool, right?"
