Rick Perry Jokes About 'Oops' Moment At GOP Foreign Policy Debate In South Carolina

During Saturday night's GOP debate, Rick Perry joked about his embarrassing Wednesday night debate moment, when he tried to list the three government agencies he wants to eliminate and was unable to do so.

"You advocate the elimination of the Department of Energy. If you eliminate the Department of Energy --" CBS News host and debate moderator Scott Pelley asked.

"Glad you remembered it," Perry interjected with a smile.

"I've had some time to think about it, sir," Pelley responded.

"Me too," Perry said.

On Wednesday, Perry struggled to name three federal agencies he would like to eliminate:

"Commerce, Education and the -- what's the third one there? Let's see," the Texas governor said.

Perry's rivals tried to bail him out, suggesting the Environmental Protection Agency.

"EPA, there you go," Perry said, seemingly taking their word for it.

But that wasn't it. And when pressed, the candidate drew another blank.

"Seriously?" moderator John Harwood, one of CNBC's debate hosts, asked. "You can't name the third one?"

"The third agency of government I would do away with -- the Education, the Commerce. And let's see. I can't. The third one, I can't," Perry said. "Oops."
