Of all the places in your body, your eyeball is the last place in which you'd expect hair growth. A young Iranian boy knew that he had a small tumor in his eye, but when he turned 19, he realized that the tumor had some hair on it. Typically, this type of tumor isn't cancerous, but it call grow cartilage and even sprout hair and sweat glands. Lucky for the guy, doctors managed to remove it from his eye.
