Baby, it's Hot Inside! Filled with PG-rated holiday-themed line drawings of the most notable celebrity Chrises from the worlds of Hollywood, music, and sports, including Hemsworth, Evans, Pine, Pratt, Rock, Rinaldi, Jericho, and even Noth, Walken and Waltz, and maybe even a Kris Kringle or two, all of whom are illustrated in-and-out of a variety of holiday-themed outfits and situations, this ode to boy -- uh, I mean joy -- also features enough holiday-themed mazes, fill-in-the-blanks, crossword puzzles, games, cryptograms, and full lyrics to traditional holiday songs to make your days merry and bright (and your nights a little less silent).   Grownups will be delighted to use crayons, pencils, or even the coal they receive to draw in Chris Evans' yule log, add some silver bells to Chris Pine's Ugly Christmas sweater, throw some shade on Chris Hemsworth's winter pelt, or add an icy sheen to Christopher Walken-in-a-Winter Wonderland.   The perfect gift for anyone -- be they naughty or nice -- or to stuff your own stocking, I'm Dreaming of a Chris for Christmas is sure to inspire everyone from the most serious of Scrooges to the most ho ho hos.
