Usually when I get a letter from Nigeria someone's either asking for my bank account information so they can transfer millions of ill-gotten $$$ into it and then they'll transfer most of it later on to another account but I get to keep some of it for my own trouble or, in a variation of the above scheme, they need me to first send them a few thousand $$$ up front so they can then send me the several millions of dollars. The last one I received was a beg for someone to send high end medical equipment (to be paid for later, of course) over there as there was a huge need for it right now and a lot of money to be made in the market. Cisco training now....this is a new one.
