Husky happiness is contagious, and the evidence of this indisputable fact is this video. The husky featured couldn't possibly be more joyful, playing at full speed in an enormous pile of autumn leaves. It makes the little kid in us want to run and jump in the leaves, too! This has to be one of the best parts of watching summer change into fall.
