Precious Dreams to Everyone

Elise's bedtime script (must be repeated with exactness each and everynight):

Elise:  Precious dreams to everyone.

Mom:  Precious dreams to everyone.

Elise:  Are you going to wake me up?

Mom:  Yes, I'm going to wake you up.  (No short answers here.  A simple yes simply won't do.)

Elise:  Goodnight.

Mom:  Goodnight.

The end.

I have no idea where she came up with the "precious dreams" thing.  I can't think of any references, but who knows.  I remember when Frank was about this age, he had a three part exchange as well, but I can't remember exactly what it was.  It didn't involve precious dreams though...
