Shonda Rhimes, commander in chief of ABC's Thursday primetime schedule -- and probably the only TV producer in America with household name status -- turned up on "Jimmy Kimmel Live" Thursday as part of a bet to herself, and as part of an early promotional stop for her new book, "Year of Yes," arriving in November.

Just about anything Rhimes does and says in a public forum these days or nights is noteworthy because she is -- without question -- one of the genuine arbiters of a major cultural and TV shift underway right now. Viola Davis won the Emmy for best actress this past Sunday for "How to Get Away with Murder," which though produced by Peter Nowalk is a Shondaland production. Without Rhimes, Davis might not have made history as the first African-American woman to win a best actress Emmy.

So what does Rhimes have to say about the power of "yes," and her new book, and her vestigial fear of Jimmy Kimmel, and public appearances in general? Check out the clip. But she also addressed this topic at the recent press tour as well -- without making mention of the fact that she had based an entire book on the premise. Here's what she said in August:

"I did 'The Mindy Project' [on the episode 'The Devil Wears Lands' End' last October] because I made a ridiculous promise to myself that I would say yes to all the things that scared me for a little while. And, unfortunately, Mindy called me up and asked me to guest star during that period of time, and so I had to say yes...

"And it is not something that I ever would have done. I really am not that kind of person. But it actually turned out to be fun. And would I do it again? I don't think so. But I did it. They were really, really nice to me and really kind and made me look good and pretended that I knew what I was doing. What I learned from the experience is that I don't know a thing about acting, and it's an incredibly hard thing to do because I cannot walk and talk at the same time. And if you see, if you watch the episode, you can see that I am not walking and talking at the same time."
