Most little girls would be totally excited at the prospect of having a baby sister. But this two-year-old was not too happy to learn that her newborn sibling was on the way home - and she certainly wasn't shy to show it. The adorable girl, named Piper, was filmed by her father launching into an incredible temper outburst and consistently refusing to have anything to do with her sister. The video has since gone viral reaching over 400,000 views on YouTube in just three days.
