Yesterday, April 14, was "Black Day" in South Korea. Kind of like the anti-Valentine's day, April 14 is when people who are not in love wear black and eat black food. South Korea marketers have hatched special days for the 14th of each month to create a calendar with a crapload of love holidays. Black Day has become really popular, but Green Day, August 14 — where couples are supposed to drink cheap beer that comes in green bottles and walk in the woods — hasn't caught on. [MSNBC]
