The official U.S. Instagram account for Kit Kat released what one Mashable editor called "the best piece of internet today." It includes Chance the Rapper. In a fuzzy animal Halloween costume. Singing his own melodious, adorable rendition of the Kit Kat song. If that doesn't make you want a Kit Kat bar, nothing will. Chance the wRapper... this is more than a bit surreal and I absolutely love it. https://t.co/y7alXeALa9
