Pointing to massive war-time tax cuts, physicians from the Congressional Budget Office diagnosed President Bush with attention-to-deficit disorder Tuesday. 'The president exhibits all the symptoms of ATDD: impulsiveness, restlessness, inability to focus on mounting U.S. debt likely to reach $400 billion by the year's end,' Dr. Terrence Spellman said. 'Failing to address his affliction could lead to serious long-term fiscal health problems for future generations of Americans.' To treat the president's ATDD, Spellman prescribed Ritalin and an introductory course in high-school economics.
