Ha ha ha! I guess you've recieved some of the legendary Nigerian fraud (aka 419) scams. These scams are really the bane of the country because of it's wide practice through out the world. It's stereotyped Nigerians as con-artists and fraudsters. But really it's a reflection of the dire corruption that has totally infected the entire culture of the country. Many people see 419 as a regrettable but acceptable means of acquiring money. This is very big shame.
