That is brilliant! I guess people must still fall for these cos they just keep coming.
My favourite had the subject line TOP SECRET and claimed to be from the Nigerian Space Program. (You didn't know Nigeria had its own space programme? Well of course not, it's top secret, silly! Duh!) Apparently one of their astronauts went up on a mission some years back and his ship malfunctioned meaning that he got stuck in space. So there the poor chap has remained to this day, just like Major Tom floating in his tin can. And of course in the mean time, he has accumulated all this back pay, and they just need someone's bank account details so that they can find somewhere to keep his dosh until he is rescued.......
