Nearly everyone, at this point, has received the ubiquitous Nigerian 419 advance fee email scam. An unsolicited email comes from someone in Africa, claiming that a long-lost relative died, or that the South Kenyan lottery just awarded you 18 million dollars. All you have to do is pay a fee to help the money clear regulatory hurdles, or give them your checking account information. Some have speculated that the emails are deliberately bad, so that only the most vulnerable and easily confused will respond, as they're the easiest marks.
Personally, the best I've ever seen was a physical letter, sent to my roommate in college. And yes, it was still in broken English.
Nobody falls for these, right? You'd have to be, well, gullible is a nice way to put it. Well, according to Above the Law, one lawyer did, and took his clients along for the ride. Now, his clients are out $200,000, and he will be benched by the Iowa Bar Association for the next year, at least.
