"Mommy, Wheres Yours Pinky?"

So yesterday I was getting out of the shower and my two year old son asks me, "Mommy, wheres yours pinky?"  Now I don't know where he got this "pinky" business cause I only teach him correct words for body parts.  I explained to him that girls don't have pinkies, only boys. That seemed to make sense to him.  One awkward conversation down, one million to go.
