Best-known episode: "The Label Maker"
Hello, Newman. A postal worker who lives down the hall from Jerry and Kramer, Newman is the show's primary antagonist: "Mark my words, Seinfeld! Your day of reckoning is coming, when an evil wind will blow through your little playworld and wipe that smug smile off your face!" There's no obvious reason for him and Jerry to be sworn enemies — he's no more self-absorbed or scheming than any of the lead characters. But he did work the same postal route as David "Son of Sam" Berkowitz, which can't be a coincidence. GAVIN EDWARDS
