Why? Adam and Eve

Lately with an active 4 year old mind I have not felt like answering all of the billions of whys? I know this is how we learn but this is how it has been going for us lately:

Morgan:
Why can't we just wear our underwear outside?
Me:
Adam and Eve
Morgan:
Why do we have to dry off when we get out of the bath?
Me:
Adam and Eve
Morgan:
Why do I have to wash my hair?
Me:
Adam and Eve
Morgan:
Why do I have to brush my teeth?
Me:
Adam and Eve
Morgan:
Why do we have to take medicine?
Me:
Adam and Eve
morgan:
Why do you have to drink poo-poo medicine?
Me:
Adam and Eve

So, I know I am blaming it all on them but now when she asks me a question she is answering it herself: Mom why.... because of Adam and Eve?
