@cbsnews: A Minnesota man sprang into action when he spotted a school bus moving past him as its driver experienced a medical emergency, jumping aboard to help stop the vehicle with nearly 20 students inside. Ebro Ahmed, 27, initially shifted the bus into reverse by mistake before managing to put it in neutral and pull the brake. No one was injured. Ahmed credited his favorite TV show, "Grey's Anatomy," with teaching him the importance of staying calm in an emergency.
