UPDATE: The story behind the photo..
The third and final debate between the 2008 U.S. presidential nominees had just ended. Democratic nominee Senator Barack Obama and Republican nominee Senator John McCain had just shaken hands moments before and turned away from each other, when Senator McCain suddenly lunged forward with his hands out in front of him and stuck out his tongue.
It appeared to me that McCain was reacting to moderator Bob Schieffer informing him that he was headed the wrong way off the stage, that he was not supposed to be following Senator Obama, but was supposed to be heading towards his own wife and family around the other side of the table.
In any case, when I saw McCain lunge and his hands start to come up I hit the shutter and made two frames before it was over. Some other photographers who were there expressed surprise when they saw my picture and said they had never seen it happen at all and asked when it had occurred.
