On Seinfeld:
"Men in the Seinfeld universe become super-intelligent after they stop having sex for a period of time, because the majority of their brainpower is normally focused solely towards obtaining sex, so a celibate man's brain becomes free to think about other things. For the same reason, going without sex has the opposite effect on women. Since men are always so obsessed with sex, women can get sex so easily that they take it for granted, and barely have to think about it at all. A celibate woman's brain becomes cluttered up thinking about sex, and she becomes stupider. This was demonstrated by George becoming an Omnidisciplinary Scientist and Omniglot after going without sex, while Elaine became The Ditz".
