(S06E22) This episode kicks off, as so many do, with an episode of the Krusty the Clown Show. It seems Krusty got into some hot water with a sexual harassment lawsuit, so his special guest that day is a woman named Officer No Means No. Meanwhile, Bart enjoys his breakfast of Krusty-Os, which contain a special prize inside: one jagged metal Krusty-O.

Bart swallows the jagged O unknowingly, and begins to feel the effects while in class. He begs Ms. Krabappel to let him see the nurse, but she thinks he's faking. Bart tries to persuade her by insisting that if he dies, she'll get in trouble, but according to the school charter, "No teacher shall be held accountable if Bart Simpson dies." Bart is forced to finish his test, and finally Ms. Krabappel let's him see the nurse, who also happens to be Lunch Lady Doris due to budget cuts.
