50. 'Crazy' Joe Davola
Best-known episode: "The Opera"
He leaves his apartment door open in order to encourage intruders. He cries while lifting weights. And he has no problem roundhouse kicking Kramer in the head. But more than anything, "Crazy" Joe Davola (Peter Crombie) lives up to his nickname with his various attempted attacks on Jerry Seinfeld, whom he blames for rejecting a TV script he wrote, making him one of Seinfeld's most nuanced and most psychopathic characters. Not that there's anything wrong with that. After all, to quote Davola, "Fear is our most primal emotion." KORY GROW
