Dramatic Delivery: The World’s First Cinematic Cryobank

'Delivery Man,' which comes out tomorrow, stars Vince Vaughn as David Wozniak, a man whose stalled life is turned upside down when he finds out that he's fathered 533 children via sperm donations he made 20 years earlier. While he's still wrestling with the magnitude of this reality, David's hit with a lawsuit from 142 of the 533 twenty-somethings who want to know the identity of the donor. How plausible is that plot line?
