The most endearing character in Disney’s new “Frozen” is Olaf, the sunny-natured little snowman who loves warm hugs. If you’d like your very own Olaf to brighten your refrigerator, here’s your chance to win one! Send me an email at firstname.lastname@example.org with Olaf in the subject line and tell me your favorite way to decorate a snowman. Don’t forget your address! (US addresses only) I’ll pick a winner at random on December 3. Good luck!
