The Late Late Show needed a guest host when James Corden had to head to the hospital for the birth of his daugther, and James's good pal Harry Styles rushed to CBS to guest host an episode. Harry kicks off the show with a monologue about the Alabama special election with Roy Moore and President Trump's plan to get back to the moon before moving on to a Christmas edition of Dogs in Sunglasses.
