Britain's Got Talent contestant Susan Boyle blows the audience away with her rendition of "Cry Me A River" by Elaine Page. Watch as the audience and judges initially look at her like she's a complete doofus, but in the end give her a standing ovation for her amazing performance which they were completely shocked by. This is an example of why we should not stereotype people based on their looks and/or background and doubt their abilities. This should be a lesson to all of us.
