I used to think Jerry Seinfeld was among the greatest comedians, but it wasn't until I saw Curb your Enthusiasm that I realized Larry David was the true genius behind Seinfeld (the show). His act is moderately entertaining at best. If you watch his documentary, "Comedian" you may also get the impression that he kind of an arrogant %&*@. However, I still maintain that the "Seinfeld" was the best sitcom of all times.
