I don't really see him as being any mor eprofessional than any other actor who has been on more than one sit com in his career. As far as actors go, I think he's a very good "every man", much like Phil Hartman was for Saturday Night Live. He is indeed a very versatile actor, who can take on any role and own it... but not any more than any other professional actor.
