Funny Car Conversation with Sarah

I'm driving with all the kids to Walmart and we're listening to a children's songs CD and the song Jack and Jill comes on, and it gets to the part where "Jack fell down and broke his crown," and:

Sarah: (says to herself) Broke his crown?... Mom, is crown another word for head?
Mom: yes it is
Sarah: So he broke his head?
Mom: ya, I guess so
Sarah: wow...that's gotta hurt.
