Creepy Children

I have a two and a half year old who loves telephone conversations. His dad called to tell us he was running late and I asked our son to say goodbye.
In this deep, demon like voice he says "Bye daddy I love you." I let out a little giggle then my boy looks at me dead in the eyes and says (in his normal voice) "bye daddy's blood, bye."

We have just learnt about blood from the movie 'Bolt' and how it comes out of you when you get hurt.
