Guy gets a typical 419 scammer email from an "exiled dictator" - "We need you to hide our millions, in exchange for a cut of the proceeds. [etc.]"
Guy responds, and after a few emails and calls (during which he keeps "forgetting" to give them his account and routing numbers), "discloses" to scammers that he wants to sell some stolen laptops in their country - they can keep 20% of the proceeds (they're like, "Oh Sure. We'll send you your 80% share, honest...") -- the only wrinkle is he doesn't have enough funds to pay for the shipping, so he will need them to pay shipping charges collect.
After hemming and hawing and guy threatening to walk, the scammers agree.
Guy then buys two used washing machines on craigslist for 20 or 30 bucks, removes the motors and guts, and then fills them to the very top with cement. Then he crates them up and ships them, air freight, to their country.
Hilarity and death threats ensue.
