My Brain Is Where?

Apparently I need to do a school unit on the body.  Here's a recent conversation I had with Libby while I was putting her shoes on:

Libby (chanting): Your brain is your crotch.  Your crotch is your brain.  Your brain is your crotch.  Your crotch is your brain.

Me:  Stop it.  Why are you singing that?

Libby: Because it is!

Me:  Uh, no it's not.  Your brain is up in your head. 

Libby:  No!  Your brain is down here in your pee-pee parts! 

Me:  No, that's not true.

Libby:  IT'S REAL!

Then she ran off to play.  

I guess it's time to pull out the body book.
