At a recent glittering dinner party in honor of George and Laura Bush last month the ex-President praised Queen Elizabeth as hundreds of plates of piping hot food were all served promptly... despite a five hundred yard trek down three flights of stairs from the Banqueting Hall to the kitchens.
"It IS a long way," the Queen replied sweetly, "luckily one has a very large dumb waiter; makes all the difference."
President Bush paused a moment before eventually replying:
"Ma'am, we, uh, also have 'em in DC and in Texas, only political correctness means we have to call 'em 'developmentally challenged catering operatives'.
"There's one in the White House waiting for his contract to be renewed on November 6th!"
