Hi, I'm Mohammed Abacha, the finance minister of Nigeria.
So it's like this: I've embezzled 25 mil from the Nigerian treasury, and my only problem is I need a foriegn bank account to transfer the funds. Crazy isn't it? So I'm sending out a spam email to 100,000 strangers, hoping that one of them will be kind enough to let me transfer my fortune into their bank account. I'll even give them 30% of the money. Aren't I nice?
