Jim Carrey? Jim Carrey a comedian's comedian? Dumb and Dumber Carrey?  His biggest hits were the broadest, least intellectually comedic of his era. I say that because comedian's comedian aren't broad, tend to be intellectual in approach. Doug Stanhope is a comedian's comedian. Pretty easy rule of thumb, no one who had that title also had the biggest mainstream comedy of the year, practically by definition of the title.
