Not to be outdone by her erstwhile partner in sin, who has now been seen suavely clothed in TV talkshows and hirsutely unclothed in Playgirl magazine, Bristol Palin has agreed to appear as herself on the ABC Family drama series “The Secret Life of the American Teenager.” The 19-year-old daughter of Sarah Palin will be featured in an episode dealing with the consequences of condomless fornication and teen pregnancy. Since Bristol did not get famously pregnant all by her lonesome self, inquiring minds want to know if we’ll get to see her “Makin’ Whoopee” with Levi Johnston. To boost ratings, ABC Family should change the title of the show from “The Secret Life of the American Teenager” to “The Secretions of the American Teenager.” Reality TV doesn’t get better than this. It isn’t porno, it’s Sex Education.
