Chappell is the best. I kinda feel bad for him because I'm sure its hard for anyone to adjust to such rapid fame. I'd probably wig out myself if I were in his shoes.
I heard a great interview with him on NPR a little while back. He had a very interesting childhood, switching from living with his mom in DC during the crack epidemic and rural ohio with his college professor father. His diverse upbringing no doubt contributed to his insightful view of life.
I wish him all the best.
