Norway has turned to a bit of toilet humor in response to U.S. President Donald Trump's recent comments insulting the Scandinavian country and the Nobel Peace Prize.

After Trump called Norway a "shithouse," the country's tourism agency published a guide to "some of the world's most beautiful and spectacular toilets " sprinkled across the stunning Norwegian landscape.

Trump's comments on Sunday at a political rally in Port Huron, Michigan, ahead of the U.S. midterm elections were not the first time the U.S. leader ranted about Norway or the Norwegian Nobel Committee.
