Best-known episode: "The Maestro"
His job description — conductor for the Police Benevolence Orchestra — is hilarious in and of itself. But it's the Maestro's pomposity that's the ultimate joke. In the world of Seinfeld, lowbow art (comic books Rochelle, Rochelle) always trumps the boring highbrow stuff (classical music, opera); in that way, the show pioneered the celebrate-trash aesthetic of our times. And what could be more insufferable than a low-rent Leonard Bernstein wanna-be (played with brilliant cluelessness by Mark Metcalf, a.k.a. the sadistic Neidermeyer form National Lampoon's Animal House) who insists on being called the Maestro?
