Fourteen million (and counting!) views later, Ethan's video has become one of the most watched videos on the site and recently won, by popular vote, the title of "Most Adorable" video in the 2007 YouTube Video Awards. His video also is being used by AIG in a nationwide advertising campaign and has appeared on many talk shows and news programs. You can watch it here: "http://www.youtube.com/watch?v=wXIfU-87TZo"
