You show a beautiful book and as you flip through the pages they see Black & White picture of a Christmas tree on each page.   You flip through again and this time all the pages have changed to a green tree.  Flip through one more time and the tree is now fully decorated on all the pages.   As a killer ending you roll the book up and pull out a string of 18 lite LED Christmas lights.
