BARACK OBAMA
The former president got a rock-star reception when he made a surprise appearance at Michelle Obama’s book tour stop in Washington. Obama dropped in on his wife Saturday as she promoted her new memoir, “Becoming,” to much applause. That led him to compare himself to rapper Jay-Z. “You know when Jay-Z comes out during the Beyonce concert?” Obama told the crowd. “It’s the same thing. It’s just a little sample to enhance the concert.”
