After having trouble trying to solve a brainteaser and other mounting evidence, Lisa fears that the Simpson gene, Grampa has told her about, is afflicting her. Meanwhile, Grampa's friend Jasper places himself in suspended animation in Apu's freezer. Jasper wants to see the future. Seeing an opportunity to make money, Apu turns the KWIK-E-MART into a FREAK-E-MART. Lisa gathers evidence on her newfound stupidity and fears she will turn into another Simpson moron. She gives an editorial on the news on how people should nurture their brains while they still can. Homer tries to show her that not all Simpsons are troglodytes. He gathers them on the front lawn and asks each what they do. It turns out all the men ARE idiots and the women, by comparison, are freakin' geniuses. Lisa feels relieved with the proof. Jasper awakes from his frozen state and Apu loses his gimmick.
