I loved listening to him think through the answers. He varied his speed, volume and tone very effectively.
What I didn't like
I would have enjoyed a few more personal stories in his journey on this obsession.
My overall impression
I loved the whole show! He approached his obsession from so many angles; it just keeps surprising and amazing you. How many people can speak that fast, let alone think that fast. What a fun experience for people of all ages and interests!
