Twyla Tharp has moved her whole life. She dances - she’s danced and choreographed professionally for 55 years now. She exercises. And now, she has a book. “Keep it Moving” is a manifesto on living your life with purpose and vigor, which Tharp has in spades. Seriously, she’s one of the most insightful, hilarious, brilliant and sassy guests we’ve ever had on the show. She’s a legend in the world of dance. She also kind of makes fun of Jesse’s dog, and chides him for not moving enough.
