January 19 is National Popcorn Day. While the origins of this holiday are unknown and there is no official documentation declaring this a real "National" day, there's no reason to kick back with your favorite bowl of popcorn. I'm partial to kettle corn and my kitties are nuts for lemon and salt.
Here are some popcorn books to get you hungry:
 The Popcorn Dragon  by Jane Thayer
 The Popcorn Book  by Tomie de Paola
 Popcorn!  by Elaine Landau
