Our favorite green curmudgeon is back on the air this holiday season, along with his faithful sidekicks Mary Lou and Max the Dog, to solve a brand new mystery. The children of Whoville’s letters to Santa have gone missing and it’s up to the Grinch (S.N.L.’s James Austin Johnson) and his crew to get to the bottom of things—and to clear his name. Along the way, Jon Hamm, Danny DeVito, Tony Hawk, and other familiar faces drop in to persuade the Grinch (to little effect) of the joys of Christmas. But even the Grinch’s doom and gloom can’t sour the fun of this capering podcast, which is a perfect holiday listen for the whole family. —Paulina Prosnitz
