Nigerian scam - with a difference!

I get the odd hundred or so Nigerian scam emails per second, just like the next guy. Usually I just delete them, but this one warranted further inspection.

Major kudos to the guy/gal who did this - I presume they hacked the scammer's mass email system, and changed the text ever so slightly! Here is the source of the email, with some info replaced with ****'s once it hit our office mail server:

Dont trust nigerians - Nigerians are the most idiot pice of shits in the world

I'm quite happy to get this email, if it means that this scammer has sent one less real scam. Hopefully this stopped thousands of scams, who knows? At least it made me laugh :D
