This has got to be the most honest spam I have ever received. And polite to boot. It certainly made me laugh:

Hello, i am here to propose you a deal. I want to be fair, I have stealed Canadian Bank accounts, and credit cards. I spam evry day for credit cards and Bank accounts. Can you accept to send to you the money from these stealed accounts and you to cashout? After that you will send me via Western Union 50% of what i send to you. I can send up to 5k per day.. We can make nice profit… Please reply me —@yahoo.com if you are interested. Thank you very much.
