Gabriel Winant lays out a strong case at Salon.com: Rush Limbaugh just can't stop talking about butts.

Critics say that Rush Limbaugh likes to talk out of his ass. But that's only half the story: Rush can't stop talking about butt, either. It's too bad that Sigmund Freud's long dead, because Rush is the old shrink's dream patient, with an obvious diagnosis: Limbaugh has an anal fixation.

Based on Winant's long list of evidence, it does make you wonder whether Rush needs to go see a therapist to figure out why it is that this "family values" guy has now divorced three women. Maybe we've got yet another classic case of reaction formation on our hands, and that would certainly explain a lot of Limbaugh's hostility.
