Nobel Peace Center, Oslo

Every time I pass this building I'm reminded of the time Barack Obama visited Oslo to accept the 2009 Nobel Peace Prize, and a team of "graffiti" artists used a stencil and a high-pressure water gun to spray the words "Obama: You won it, now earn it!" on dirty pavements in the city. Don't get me wrong, I'm a fan of Barry O, but he should never have accepted that prize after less than nine months in office.
