CRAWFORD, TXAccording to White House sources, following yet another disappointing grading period for the nation he leads, President Bush hid the national report card in his bedroom sock drawer Monday. 'We, as a nation, got a D in international relations, a D in economics, and an F in military history,' Bush reportedly said. 'We must work hard to make sure no one finds out about this.' Critics say the report-card-hiding effort is immature, and point out that the sock drawer is the first place The New York Times will look.
