A health teacher had a stroke that completely obliterated her hearing and sight, and left her paralyzed. Amazingly, she still taught for a good three years afterwards. Students would smoke pot in her class and whatnot, and she was never the wiser. Finally, they got her an aide to help her out, and then realized that they could just fire the cripple and have the aide teach the class. The fact that the teacher didn't resign immediately, or they didn't come to this decision earlier, boggles my mind, but hey, Kansas schools.
