"Merry Crisis" or "Merry Crisis and a Happy New Fear" is a slogan that appeared as graffiti in Athens during the 2008 Civil Unrest in Greece. Earlier, a picture of such graffiti appeared on the cover of Vavel Magazines's 2007 Christmas special. The British anarchist publication Occupied London states that it was "one of the main slogans of the 2008 revolt."
