This was at the White House Correspondence's Dinner and President Obama was as cool as a cucumber just hours before he directed the raid that killed Osama Bin Laden, but at the time no one knew that was about to happen.
Watch Donald Trump. He could not handle the joke -- his face frozen with rage.
Think he could handle the job of being President? Not a chance. Being President of the United States is a serious job with real lives on the line, even when jokes are being told. It ain't Celebrity Apprentice!
