Randall over at BWG.com (Big White Guy in Hong Kong) explains.
Because July 2011 will contain five Fridays, five Saturdays and five Sundays, under feng shui it is called a “money bags” month because this only occurs once every 823 years. So when you receive an e-mail chain letter mentioning this, you must forward it and you will receive money within four days.
Except as he notes, the facts get in the way.
