President Obama is famous for his addictions: cigarettes, dawn workouts, and his beloved BlackBerry — which he got to keep in January after advisers gave him the thumbs up. His e-mail address, unfortunately, is classified, so comedy troupe Kasper Hauser imagined what the president’s inbox might look like with their new book, “Obama’s BlackBerry” (Little, Brown) out tomorrow. The result? Political parody at its finest.
