I wouldn't include Jonathan Winters in that second category -- I'd put him in with the legends. Also add Jack Benny, Phil Silvers, maybe Groucho and I'm sure there are a few others that should be nominated to "legends".
I agree too many comedians don't know what it means to be funny anymore. Most think punctuating sentences with curse words is comedy. Give me Rodney Dangerfield any day.
Don't forget Bob Newhart. His driving lesson routine is a classic!
