More conversation from the backseat...

On our way home from the kids getting some shots, we crossed over a train track.
EJ: Mom, we have NEVER seen a train on the track.
Me: You know what?  On the night you were born, Dad and I were on the way to the hospital and we got stopped by a train on that track.  We thought we might have you in the car.
EJ: (thoughtful silence) Mom, how do babies get out of the belly?
Me: (trying not to wreck car... not really prepared for this question and all the roads it might lead down...) Well, there are several ways a baby can be born.
EJ: How did Gracie and me get out?
Me: (crap... sigh) You came out through my vagina.
EJ: Gracie has a vagina!
Me: Yes, yes she does.
EJ: WOW!  Did you vagina EXPLODE?
Me: you don't know the half of it kid!) Not really.
EJ: Oh.  (thoughtful silence) What happened if you needed to pee?
Me: (really? that's the follow up question?  let me pull out my Mister Goodbody outfit.) I don't pee out of my vagina.
EJ: Where do you pee from?
Me: My urethra.
EJ: Oh.  Where does Gracie pee from?
Me: Her urethra.
EJ: Oh.  I pee out of my peanut.
Me: yup.
And that was the end of that.  I'm SO glad the "Where do babies come from?" question wasn't a follow up.  I also hope that he doesn't decide that kindergarten is the place he should spout out his new knowledge.  I was pretty proud of myself for not loosing my cool and just answered the question as well as I could.
