Comics like Red Skelton, George Burns, Jackie Gleason. Bob Hope. They dont make em like that anymore. Funny right up to the day they died.
Robin Williams, Jim Carrey,Jonathan Winters, others like them, Their Schtick gets old after a while. Its the same old ,same old.
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".
Cosby is staying funny as time goes by. Milton Berle did not. Richard Pryor, I don't think he did. George Carlin isn't funny anymore, though I must admit the last time I saw him on The Tonight Show w/Jay Leno and Ann Coulter he did have a funny routine.
I love the humor of Jonathan Winters. As far as the younger commedians out there, I think Jim Carrey is pretty talented. I use to like Robin Williams, back when his humor was pretty much silliness, but then he had to get so political and bitter.
