Poor Michelle Obama. She was fielding questions about life in the White House  from the offspring of White House staffers on Take Your Child to Work Day when her family’s dog Bo upstaged her, barking and tapping her forearm with his paw to get her attention. (See the video of Bo ) As Obama tried to push ahead and continue talking about being the first African-American first lady, Bo would have none of it and continued to bark at her. After she pet the dog and told him he was going to have to leave the room because he was disruptive, the children said, “No!” So Obama relented and walked Bo over to the children to let them pet him.
