In the video above, AP Chairman Dean Singleton put his foot severely in mouth at the Associated Press' luncheon — where the featured guest was Sen. Barack Obama.

Watch a few seconds in as Singleton accidentally calls him "Obama bin Laden" while asking a question about national security.

Singleton said: "You said you want to reduce the number of troops in Iraq, can you imagine shifting a substantial number to Afghanistan where the Taliban has been gaining strength and Obama bin Laden is still at large?"

Obama replied after hearing laughter from the crowd.

"I think that was Osama bin Laden," he said.
