"Vagina, Vagina, Vagina." Such was the conversation between Stephen Colbert and Naomi Wolf on last night's The Colbert Report, during which Colbert interviewed Wolf about her latest (lackluster) tome, Vagina: A New Biography. The vagina, says Colbert, "has a certain mystery.... Does Tom Hanks fit up there?" .... Indeed. The two discuss women's sexual proclivities—they rarely come (in hetero sex) and, regardless of sexuality, they usually are not stimulated until foreplay has begun. Yes, we all know this.... It's still very entertaining.
