Being the President of the United States of America is no child's play. Or maybe it is if you are Barack Obama! He's one of the most sought after diplomats on the planet. But even though he is the leader of the world's most powerful country, Obama knows how to have fun. He's not an uptight politician, he's more like an old fun-loving uncle. He's smart, sensitive and loves to express his witty side. So whether it's fun with the kids of his staff or the staff members themselves, Obama leaves no chance to turn a rather uneventful day into a day of laughter and joy! This is why he is loved by millions.
