my favorite graffiti ever was on Bolshoi Afanasievsky Pereulok in Moscow. "Революция будет! People make me sad."It wasn't clear from the placement which phrase came first. Was one artist sad because of the revolutionary's naive hope in social upheaval, or was the revolutionary trying to cheer up the sad one? It's been painted over now, but I think of it whenever I walk past the building.
