Totally Awesome! This High School in Wisconsin put together this music video - song inspired from Hall and Oats, and from the awesome dance scene from (500) Days of Summer. They had to do this music video lip singing backwards. That means they had to learn all the words to the song backwards and say them backwards. How cool is that! Just thought I would share the latest craze on YouTube. By the way go see (500) Days of Summer - great movie!!!
