That's hilarious, and it's pure Taiwan. You do have to admire the guy's ingenuity. And though you've got to feel sorry for the women, they were all willing to screw the old man just to have a chance with the handsome son; so in a sense, they deserved to be scammed. Taiwanese girls are like that, both incredibly naive and ruthlessly calculating at the same time.
A good scam artist always plays on the victims greed.
