The children return to school for the first time since the death of Ms. Choksondik in the episode "Simpsons Already Did It". During the break, Bebe (Wendy's best friend) has started to develop breasts. Though they are small (she at first thought they were mosquito bites), they prompt all the boys in town to begin to think that she is unusually smart and cool, without even understanding why. However, this causes Wendy and the other girls to get incredibly jealous, especially since Stan, Wendy's boyfriend (who hasn't asked Wendy to hang out with Stan and the other boys), is one of the boys affected. The girls begin making up malicious rumors about Bebe and accuse her of being sexually promiscuous.
