WASHINGTON — I like to think of Miss Sandra Fluke’s contretemps with the madly admired Mr. Rush Limbaugh as, well, a fluke. She objected to his joke about her being “a slut” and “a prostitute,” and hesto presto the part-time Georgetown University law student struck pay dirt. You object to my characterization of her as “part-time”? How could she be a full-time law student and still be appearing before Congress explicating the plight of coeds with $3,000 contraceptive bills or others suffering the heartbreak of being rejected publicly at the pharmacy for insurance coverage of a birth control bill? Then there was all the other media attention that came from Rush’s little joke. Yes, I see it as a fluke, defined by the Dictionary of American Slang as “a fortuitous accident.” Was not Miss Fluke felicitously named years ago before anyone ever thought of talk radio?
