"I was a mere child when the classic tear gusher Love Story hit theaters in 1970, but I wept along with the adult audience as the dying AliMacGraw told the arling Ryan O'Neal, 'Love means never having to say you're sorry.' Two years later, I saw anotehr movie, What's Up, Doc?, in which Barbara Streisand's character repeated the very same line to the very same actor. This time, however, O'Neal had an answer. 'That's the dumbest thing I ever heard,' he said."
