Lisa joins Mensa, the high I.Q. society. While there, she spends her time interacting with such geniuses as Dr. Hibbert, Professor Frink and the Comic Book Store Guy. By a twist of fate, the members of Mensa become the leaders of Springfield and try to remake the town in their geeky likeness. But the geniuses can't agree on anything and begin squabbling amongst themselves. It's up to the ultimate genius, Stephen Hawking, to intervene and set the smarty-pants straight.
