I made the mistake of watching some Discovery Health specials on zootube once and for months in just about every video I saw I had to cover the right side of the screen or that Harlequin baby would pop up there. For those who don't know it's a really bad looking birth defect. Seeing it once was bad enough but it was there over and over and over and over again and it made me feel sad especially since the people posting the videos had insensitive titles to it like "Alien baby", etc.
