Jerry Seinfeld is probably, in my opinion, one of the few 'legendary' comedians of our generation. Him and Chris Rock are the two that come to mind, when I try to think of truly great jokemakers. Most who have been listed in this thread are very well-known for their stand-up. And Jerry Seinfeld probably has great stand-up material even today, but doesn't seem to get the recognition he deserves because he has a reputation of being "clean".
