Haven't seen Curb Your Enthusiasm but it's Larry David so it's the same guy.
It's not the best show but the thing I like about Seinfeld is that the characters are not huge assholes, but assholes in very petty or neurotic ways. Everyone has those impulses that the characters have, it is just that the Seinfeld characters act on those impulses and the plots evolve out of their attempts to cover one small act of pettiness with another.
