Body Parts

Seth has been watching School House Rock and learning lots of great things.  Some of the episodes are about body parts, so he has been drawing diagrams of the body and telling me all about it.  Today he drew a picture and said, "This is your spinal cord.  It is connected to your blow hole."   I asked him to show me my blowhole on the diagram.  He told me he couldn't because its one of the body parts we're not suppose to talk about.
