I think many people have at some point run into, or at least heard about the Nigerian scam. Annoying, and at times laughable - but I would never have imagined that anyone would manage to make something like this out of the whole deal. It's a collection of correspondences between unwitting scammers and their "victims", who just happen to be fully aware that the whole thing is rubbish from the start. Some of the letters on there are pretty hilarious! It even has photos that these "victims" demand the scammer provide to prove that they're the real deal..some of them are so fake that you'll burst out laughing.

Obligatory warning: Some of the material in the linked site is of a slightly mature nature!
