It all started with The United States attacking Canada with Miley Cyrus' single "Can't be Tamed"
Canada fought back by sending Justin Bieber, and turning millions of little girls into "Belieber" zombies.
In a desperate attempt to end the war, The United States attacked with Rebecca Black's "Friday" For a long time, it was thought that the war had ended at this point.
Canada recently just attacked the United States with their newest weapon : Carly Rae Jepsen and her single "Call me Maybe" It is yet to be determined if the United States will be able to gather the strength and troops to fight back
