Here are this past week's fun facts and trivia from Believe it or No: There's only one real person mentioned in the "Harry Potter" books . . . a nine-year-old girl in Toronto named Natalie McDonald who was dying of leukemia. She was a huge fan, so a family friend emailed J.K. Rowling, who included her as a student at Hogwarts in the fourth book. The baby Pebbles in "The Flintstones" was originally going to be a boy . . . until a toy company told the creators of the show that baby girl dolls sold a lot better. Thomas Jefferson was chosen to write the Declaration of Independence over Benjamin Franklin . . . because the other members of the committee were afraid Franklin would sneak in a joke.
