Obama heard something untoward as the press entered the room.
"Uh oh," he said. "What'd you all get there," he inquired.
"A water glass," came the reply from several in the press.
"Alright," he said with unmistakable dismay in his voice, adding sarcastically, "It's the Resolution Desk. It's only like a hundred years old."
Actually it's the Resolute Desk, made from the timbers of the HMS Resolute, a gift to President Rutherford B. Hayes from Queen Victoria in 1880.
