El-bones

Cristina (after jumping off the side of the couch): Ouch!  I hurt my el-bone.  (Looking at her arm and grimacing.)

I have an el-bone.  Mommy, do you have an el-bone?

Me: I have an el-BOW.

Cristina: Aww.  We both have el-bones.  Now we can be vampires.

She went on and on about el-bones and after awhile, I tired of trying to get her to say elbows.  Not really sure how this makes us vampires?
