O.J. WATCH

As the O.J. Simpson trial trudges into its third week, the flying cultural- entertainment references rival a Quentin Tarantino film. Some citations: *Judge Lance Ito: ''I'm beginning to feel like the Rodney Dangerfield of judges.'' *Prosecutor Marcia Clark: ''Now, I know that we've all seen-or some of us have seen-Quincy (starring Jack Klugman) on TV.'' ''DNA testing is not only used to solve crimes, it has many other purposes. Some of you (jurors) talked about Jurassic Park and (how) they used it to make dinosaurs.'' *Defense attorney Johnnie Cochran: ''It was (in) A Few Good Men 'I don't think they can stand the truth.' That's what Jack Nicholson said.''... ''I've known (Howard Weitzman) for 30 years. We represented Michael Jackson together.'' *The television show that witness Pablo Fenjves says his wife was watching the night of the double murder: ''The Dynasty reunion.''
