The procedure did seem strange. But I soon learned that it was a long-established custom at most Ivy League and Seven Sisters schools. George Bush, George Pataki, Brandon Tartikoff and Bob Woodward were required to do it at Yale. At Vassar, Meryl Streep; at Mount Holyoke, Wendy Wasserstein; at Wellesley, Hillary Rodham and Diane Sawyer. All of them -- whole generations of the cultural elite -- were asked to pose. But however much the colleges tried to make this bizarre procedure seem routine, its undeniable strangeness engendered a scurrilous strain of folklore.
