read this in an article: "The first thing he was compelled to do as sworn-in President of the United States was to eat an inaugural luncheon in the Capitol's Statuary Hall - a 100-year-old event hosted by the Joint Congressional Committee on Inaugural Ceremonies and attended by 200 hungry congressmen, Supreme Court judges and other worthies - that looks like it was conceived by an obese nine-year-old on the back of a 48-hour Oreo bender."
