Barack Obama takes questions from YouTube stars

U.S. President Barack Obama picked three of the most popular YouTube content creators for an interview Thursday, hoping to reach an audience typically not tuned to the daily give-and-take of Washington and its politics.

But the weirdness, the limit-pushing, the cuteness that has contributed to the questioners' success in social media was not much in evidence. Instead, Obama encountered fairly mundane questions about current affairs.

If there were viral moments, they came during his session with a popular YouTube fixture, GloZell Green. She offered Obama three samples of her trademark green lipstick as gifts for his daughters — and for the woman she called Obama's "first wife."

Obama cracked, "You know something I don't?"

Green corrected herself and referred to Michelle Obama as "first lady."
