Update: NOT The Resolute Desk, but still, dogs off the furniture, please.
Obama with his feet on the Oval Office desk made from the timbers of the HMS Resolute and gift from the UK in 1880:
Little known fact: The desk has been modified thrice: President Franklin D. Roosevelt ordered a hinged front panel in order to hide his wheelchair, Reagan had it modded to accommodate his personal chair and Clinton had a large arc removed to enable the free movement of Monica’s bobbing head. -Assman
Pssst, Barry. That desk isn’t from Wal-Mart.
Concerned onlookers were reassured that Obama does, indeed, take good care of the desk. And moments later this was evidenced when he was seen wiping the desk down with a moistened U.S. flag. -bigfurhat
