In the same style as 419baiter.com, explain to the guy that you run an art gallery and accept artisitic submissions, which will be considered then paid for (huge amounts of course) then ask him to carve you a life size model of a Wii out of wood.
Don't worry that he says he is an accountant, he will conveniently "forget" that he is, or will have an "artist friend" that can help your gallery find the artwork it needs.
remember, he must pay for shipping, and you will pay him after your galleries "board of directors" have approved of his creation
Or just string him along with no particular purpose, after all, the more time he spends on your emails, the less time he is spending actually stealing other peoples money.
