Marcia Clark has been very, very good to Arlene Parness.
Parness, a struggling actress for 25 years, is a dead ringer for the curly-haired lead prosecutor in the O.J. Simpson trial.
Earlier this month, Parness got a national audience when she appeared with the "Dancing Itos" -- a quintet of Judge Lance A. Ito look-alikes -- on "The Tonight Show With Jay Leno."
Thursday, she was back on the show, with a rose in her teeth, dancing a tango with the double of defense attorney F. Lee Bailey.
It beats her other gigs -- co-star to a cow in a milk commercial and a corpse in the movie "Outbreak."
"This could all die down and nobody will talk to me when it's all over," Parness said. "But I'm hoping to get enough work by being Marcia Clark that people will know about me. . . . Then I could audition for sitcoms."
