Meet John: IQ 150. Plays Chopin flawlessly on the piano. Reads Feuerbach in the original German. Patented a self-flushing potty chair at age 2. Youngest graduate of Harvard. Arrested on suspicion of stalking after his apartment was found wall-papered with pictures of the academic dean and he was seated nude in front of a shrine in her honor, chanting mating rituals in an obscure Maori dialect. Would you let your daughter date him? Uh, that would be a no.
