Seinfeld Episode in which Elaine dates a guy named 'Joel Rifkin': -- there's a funny bit where the name becomes a problem to the poor guy & Elaine badgers him to change his first name to...... 'O.J.' as one possibility-only funny in the years that follow the brutal murders of Ron & Nicole by the eminently sloppy O.J. Simpson..... How could the Seinfeld Producers / writers have known ?
