I realise that related videos can have some crap that we don't wanna see, and don't wanna share, so if you wanna share a video but don't want related videos to come up use this link: www.youtube.com/embed/<VideoID>?rel=0 and replace <VideoID> with the video id (This bit of the link: http://www.youtube.com/watch?v=59LHQ1bKO-M)
