A Nigerian scheme

How many of you have either got a letter or an Email, and it goes like this:
I am ____, and my _____ was the (Moneybags) of _______[country].
I need x amount of dollars to get into the account of ( number) of billions of dollars left by Moneybags. If you send just $____, you will get a 500% return.

Well, you know what? George Bush has done about the same thing.
His message : If you let all these critters (Illegal Aliens) to do our work, and let foreigners invest in roads and businesses, we can have untold wealth. All you gotta do is give up your country.
