A long time ago, when I lived in Menlo Park, I was driving and listening to NPR, an interview show. 

A woman was talking on all kinds of topics, I kept wondering who is this. So smart, and thoughtful and well-spoken. 

Turned out it was Hillary Clinton. Up till that point I had thought of her pretty negatively. 

Had the same experience with Dan Quayle btw, no joke. He's really smart of course, we just remember him in embarrassing situations.
