Don Nelson, coach of the Western Conference in the NBA All-Star game, got bad news when he returned to his home in Alameda (Calif.) County. Nelson had been raising a pet pig, Ms. Piggy, in his back yard. Greeting him on his front door was a summons from the county telling him that he must get rid of the pig. "I'm sick about it," Nelson said. "She is a great pet. I don't know what will happen to her."
