We love Dolly Parton. She's one of the VERY few show business celebrities that doesn't come across as a little or a lot "fakey". She's a person you just feel you'd like instantly if you met her in person.
It's kind of like how I refer to Bill Murray as "America's Cool Uncle".
What is Dolly in relationship to America? "America's ..."?
I'll have to put some thought into that.
