This website has a face recognition program, where you upload a photo and then they scan through their databases to find which celebrities you look like.
When I uploaded this picture, they said I look like these celebrities:
Sarah Michelle Gellar
Be careful which photo you choose, though, or you may have the fun experience I had. When I uploaded this photo, they told me I look like these celebrities:
Chester A. Arthur
I think they threw Chester A. Arthur in there JUST to hurt my feelings.
