I've heard more than a few interviews with him. He seems like a super nice, super kind guy. Very funny with a great sense of humor. He spent all day walking around Comi-Con in San Diego with a mask of himself so no one would know or think its him.

This is pretty funny. He made time from shooting Breaking Bad to do this promo to raise money for an independent movie for Adam Carolla. Very funny guy.
