I haven't been able to find an confirmation for my favourite Dolly Parton fact (at least, I hope it's a fact), from the No Such Thing as a Fish podcast a few years back:

Apparently she grew up very close to food poverty (this bit I have been able to confirm from a bunch of interviews) and so, when she could afford to, got into the habit of keeping a sausage or similar in her handbag so that she always had a nourishing snack with her.

This appeals to me because, on top of her many achievements (including being an inspiration to Moclan females across the galaxy), it's such a human thing to do. And also because it probably meant all dogs thought she was their best friend.
