Ken Jennings, the trivia-quiz show smarty-pants who broke game show records in 2004 with his unprecedented seventy-four game, $2.52 million victory streak on Jeopardy! also knows something about urban parenting legends. Tonight he reads and discusses his new book, Because I Said So!: The Truth Behind the Myths, Tales, and Warnings Every Generation Passes Down to Its Kids. Stuff like: "Don't cross your eyes or they'll stay like that!" "Never run with scissors," and "Don't look in the microwave while it's running!" Jennings separates fact from myth in important matters like the swallowing of gum and the cracking of knuckles.
