Nigerian scammers: gone to the dogs

In a sick sort of way, I have to admire the Nigerian scammers' talent for constant innovation:

In a twist on their usual e-mail scams, Nigerian con men are taking out newspaper advertisements offering purebred English bulldog puppies for adoption. Victims who respond to the ads are informed that the puppy can only be obtained after wire transferring hundreds of dollars overseas in vaccination and shipping fees. Of course, no puppy is ever delivered.

Couldn't they apply those natural abilities to . . . I don't know, inventing something useful?
