NBC News reports: While working the ropeline outside of a Boulder restaurant, a young woman spilled yogurt on the President. After realizing what had happened, the President was laughing and told the crowd, "Oh, you got me!" He asked the people around him for a towel and the women started apologizing profusely. The President assured her she now has a good story to tell.
