I wish this site were working:

it's a whole website dedicated to messing back with the nigerian scammers. This guy requested the man carve a commodore 64 out of wood. Then he had him carve a wallace and gromit (british cartoon) out of wood. Really impressive stuff, then when the man asked where his payment was, he made up a story about how the company is all in jail.
