Send out some phishing e-mails asking for people's personal details. If you are successful, open up some credit cards in those person's name. Max out the credit cards with expensive merchandise, and then sell the merchandise. Voila! A perfect money-laundering scheme (don't tell the Feds I told you that one).

You could also try your hand at 419 scamming. I get these emails all the time from barrister smith williams from Nigeria, who needs my assistance in posing as his next-of-kin..... if you don't know about the 419 scam, it's pretty fucked up the way it works; but the scammer gets their money, and they're very successful. Google it.

Note: This information is to be used for comical purposes only. I don't condone the crimes of money-laundering and confidence scamming. If you do these things, you can go to jail. IF you get caught.
