As good for me as you!

This is the title of Hazel's newest song that she sings constantly. Anyone have any idea if it comes from something? Here are the lyrics......she is singing it right now in the kitchen with Charlie (or maybe to Charlie, I'm not sure).

"I've never had someone as good for me as you!
Never had a brother, a sister, a baby a daddy a mommy
as good for me as you, as good for me as you....

This is just so fun, not as good for me as you
Never never ever, Never Ever

(still singing) Put your cereal down, we're not allowed to put cereal up.
As good for me as you"

Now Charlie is pitching in with the "ever, ever, ever" chorus.

Some version of this song gets repeated over and over and over again all day.

What's going on inside that little world of hers?
