Miss Choksondik was the boys' 4th grade teacher. For some reason, she refused to wear a bra, often causing stray kittens to linger around her massive sagging boobs. The boys' hated her, mostly because she actually tried to teach them, and called her "Miss Makes-Me-Sick" and "Miss Chokes-on-Rocks." Although she outwardly opposed men and intercourse during her sex education classes, she had a passionate love affair with Mr. Mackey. Unfortunately, she died soon after ("Professor Chaos"/"Simpsons Already Did It"). The police found Mr. Mackey's semen in her stomach, but that isn't what killed her. To date, her cause of death is still unknown...
