For Rick Perry, laughter continues to be the best medicine as he attempts to contain the damage caused to his campaign when he suffered an embarrassing brain freeze during last Wednesday's debate.
On Saturday, the Texas governor went out of his way to joke about his "oops" moment during a foreign policy debate in South Carolina sponsored by CBS News and National Journal.
Asked at one point by moderator Scott Pelley about the Department of Energy, Perry smiled and interrupted.
"Glad you remembered it," Perry said, as his rivals laughed.
"I've had some time to think about it, sir," the CBS News anchor replied.
"Me, too," Perry said, grinning as the audience broke into applause.
