Rosie O’Donnell plays Bonnie, a no-nonsense single mom who clashes with Jack over the raising of their son, Elliot, fathered from Jack’s sperm-bank donation. Bonnie’s enraged because Jack had 12-year-old Elliot’s hair bleached blond, so she lays down the law. “”From now on,”” she tells him, “”stay out of my kid’s life. I don’t want you to see him again.”” A parallel storyline unfolds at a wedding gala, where Will poses as a tennis pro (because nobody likes lawyers); and Grace caustically toasts the bridegroom, her ex-fiancé. “”I’ve always thought about having a child,”” she says. “”But not as a husband.””
