Video sharing website YouTube has released the list of its 10 most viewed videos. The site marked its fifth birthday by announcing that viewers now watch more than two billion videos a day from the video-sharing site. Charlie bit my finger - again tops the list with 169 million views. The 56 second long clip features two British brothers, aged three and one. In the video, the younger brother, Charlie, bites the finger of the older brother, Harry. The boys' father uploaded the video online in May 2007 so that it could be viewed by their godfather, and it has since become an Internet phenomenon
